Cold case

A cold case is a crime, or suspected crime, that has not yet been fully resolved and is not the subject of a recent criminal investigation, but for which new information could emerge from new witness testimony, re-examined archives, new or retained material evidence, as well as fresh activities of the suspect. New technical methods developed after the case can be used on the surviving evidence to analyse the causes, often with conclusive results.

For the television show, see Cold Case. For other uses, see Cold case (disambiguation).

Characteristics

Violent or major crime

A leaflet issued during the "autumn of terror" in 1888, when Jack the Ripper was active.

Typically, cold cases are violent or other major felony crimes, such as murder or rape which—unlike unsolved minor crimes—are generally not subject to a statute of limitations.

Sometimes disappearances can also be considered cold cases if the victim has not been seen or heard from for some time, such as the case of Natalee Holloway or the Beaumont Children.

About 35% of those cases are not cold cases at all. Some cases become instantly cold when a seeming closed (solved) case is re-opened due to the discovery of new evidence pointing away from the original suspect(s). Other cases are cold when the crime is discovered well after the fact—for example, by the discovery of human remains.[1] Some cases become classified cold cases when a case that had been originally ruled an accident or suicide is re-designated as murder when new evidence emerges.

The John Christie murders is a notable case when Timothy Evans was wrongly executed for the alleged murders of his wife and child. Many other bodies were later found in the house where they lived with Christie, and he was then executed for the crimes. The case helped a campaign against capital punishment in Britain.

Identifying a suspect

A case is considered unsolved until a suspect has been identified, charged, and tried for the crime. A case that goes to trial and does not result in a conviction can also be kept on the books pending new evidence.

In some cases, a suspect, often called a "person of interest" or "subject" is identified early on but no evidence definitively linking the subject to the crime is found at that time and more often than not the subject is not forthcoming with a confession. This often happens in cases where the subject has an alibi, alibi witnesses, or lack of forensic evidence. Eventually, the alibi is disproved, the witnesses recanted their statements or advances in forensics helped bring the subjects to justice.

Sometimes a case is not solved but forensic evidence helps to determine that the crimes are serial crimes. The BTK case and Original Night Stalker (the latter pending trial as of April 24, 2018)[2] cases are such examples. The Texas Rangers have established a website[3] in the hopes that it shall elicit new information and investigative leads.[4]

Tunnel vision

Sometimes, a viable suspect has been overlooked or simply ignored due to then-flimsy circumstantial evidence, the presence of a likelier suspect (who is later proven to be innocent), or a tendency of investigators to zero in on someone else to the exclusion of other possibilities (which goes back to the likelier suspect angle)—known as "tunnel vision".

Improvements in forensics

With the advent of and improvements to DNA testing and other forensics technology, many cold cases are being re-opened and prosecuted.[5] Police departments are opening cold case units whose job is to re-examine cold case files. DNA evidence helps in such cases but as in the case of fingerprints, it is of no value unless there is evidence on file to compare it to.

Famous criminal examples

Lake Bodom murders in Finland is the most famous unsolved homicide cases in Finnish criminal history.[6] The tent is investigated immediately after the murders in 1960.

The identity of Jack the Ripper is a notorious example of an outstanding cold case, with numerous suggestions as to the identity of the serial killer. Similarly, the Zodiac Killer has been studied extensively for almost 50 years, with numerous suspects discussed and debated. The perpetrators of the Wall Street bombing of 1920 have never been positively identified, though the Galleanists, a group of Italian anarchists, are widely believed to have planned the explosion. The burning of the Reichstag building in 1933 remains controversial and although Marinus van der Lubbe was tried, convicted and executed for arson, it is possible that the Reichstag fire was perpetrated by the Nazis to enhance their power and destroy democracy in Germany.

Examples of criminal cold cases that ended in conviction

1950s

Victim(s)	Convicted	Location	Crime date	Conviction date	Description
Harold Blauer	The Central Intelligence Agency	New York City, New York, USA	January 8, 1953	1987	Retired tennis player who was unwittingly injected with 3,4-Methylenedioxyamphetamine (MDA) after checking himself in to the New York Psychiatric Institute for depression. The experiment was part of the CIA's secret mind-control program, MKULTRA, and Blauer's medical records were altered to hide the real cause of his death. MKULTRA was revealed to the public in 1975, and Blauer's estate was awarded $700,000 in damages in 1987.
Frank Olson			November 28, 1953	1976	A CIA bacteriologist and biological warfare expert who was unwittingly dosed with LSD by his supervisor. Nine days later, Olson had a nervous breakdown and jumped from his 13th-story room at Hotel Pennsylvania. Olson's family agreed to withdraw a wrongful death lawsuit against the agency in exchange for an out-of-court settlement of $750,000 and apologies from President Gerald Ford and CIA director William Colby. Olson's children ordered a new autopsy in 1994 and tried to reopen the case as murder in 1996 and 2012, but both requests were denied because of the previous deal.
Richard Phillips, Milton Curtis	Gerald Mason	El Segundo, California, United States	1957	2003	Two police officers shot when they pulled over a car for running a red light. Mason was arrested 45 years later after a computerized fingerprint database identified him as the purchaser of the murder weapon. At the time, he had just raped a 15-year-old girl at gunpoint at a local lover's lane, and he killed the officers to avoid prosecution for the crime. Mason's back still bore the scar left by a bullet fired by the officers as he fled.

1960s

Victim(s)	Convicted	Location	Crime date	Conviction date	Description
Irene Garza	John Feit	McAllen, Texas, USA	April 16, 1960	December 8, 2017	A 26-year-old beauty queen who disappeared when she went to church for confession and was later found raped and murdered in a canal. Feit, a 27-year-old priest at the church who later pled no contest to raping a parishioner, and left the priesthood in the 1970s, was a suspect since the beginning, but little investigation was made due to the opposition of long-time district attorney Rene Guerra (1980-2014).
John Orner	Edward Freiburger	Columbia, South Carolina, USA	February 1961	2002	A 60-year-old cab driver who was robbed and murdered on the job with a .32 H&R pistol. Freiburger, then 19 and a soldier stationed at nearby Fort Jackson, became a suspect when it was discovered that he purchased the same weapon at a local pawnshop only hours before Orner received his last dispatch call, after which he went AWOL. Freiburger was stopped by Tennessee State Police a month later and found with the gun in his possession, but ballistics tests were inconclusive and he was never charged. In 2002, a private firearms examiner working for the South Carolina Law Enforcement Division cleaned up the slugs and matched the bullets to the gun.[7]
Malika Maria de Fernandez	Peter Reyn-Bardt	Wilmslow, England, UK	June 1961	December 1983	Reyn-Bardt, De Fernandez's estranged husband, made a detailed confession about how he had murdered, dismembered and disposed of her body in the bog behind his home after peat cutters found human remains there, 22 years later. Although these remains were later determined to be thousands of years old from Carbon 14 testing, Reyn-Bardt's confession was considered enough evidence to convict him of the murder of his wife, whose body was never found.
Addie Mae Collins, Cynthia Wesley, Carole Robertson, Carol Denise McNair (plus 22 injured)	Robert Edward Chambliss	Birmingham, Alabama, USA	1963	1977	Victims of the 16th Street Baptist Church bombing. Although the FBI had identified Chambliss, Blanton, Cherry and a fourth Klansman, Herman Frank Cash, as the perpetrators already in 1965, no arrests were made for political reasons, and the case was shelved in 1968. Cash died in 1994 without being prosecuted.
	Thomas Edwin Blanton Jr.			2001
	Bobby Frank Cherry			2002
James Keuler	Samuel Evans	Seattle, Washington, USA	June 1968	2011	Evans, already incarcerated for other crimes, entered an Alford plea after DNA linked him to Keuler's crime scene.[8] Oldest case ever solved using DNA evidence.[9]

1970s

Victim(s)	Convicted	Location	Crime date	Conviction date	Description
Helen Betty Osborne	Dwayne Archie Johnston	The Pas, Manitoba, Canada	November 13, 1971	December 1987	A Cree Aboriginal woman abducted while she was walking home at 2:30 pm and subsequently beaten, raped and stabbed over 50 times. Although four Caucasian men were implicated in the murder, only Johnston was convicted for it after 16 years, and the case was officially closed on February 12, 1999. The government of Manitoba officially apologized for its poor handling of the case on July 14, 2000.
Jackson and Daisy Shley	Samuel Evans	Seattle, Washington, USA	January 9, 1972	2011	A couple attacked during a home invasion. Jackson was murdered and Daisy was abducted and raped. Evans entered another Alford Plea for the murder after his DNA was matched to semen recovered from Daisy's clothing. Daisy died of unrelated causes in 2007, before Evans was identified.[8]
Steven Stayner	Kenneth Parnell	Merced, California, USA	December 4, 1972	1981	A seven-year-old boy kidnapped and held in captivity for eight years by Parnell, a pedophile. After Stayner hit puberty, Parnell lost interest in him and kidnapped five-year-old Timmy White from Ukiah, California as his replacement. However, Stayner and White escaped on March 1, 1980, while Parnell was at work, leading to his identification and arrest.
Joseph, Julie, Joseph Jr. and Josephine Otero	Dennis Rader	Wichita, Kansas, USA	January 15, 1974	August 18, 2005	A family victim of "BTK", a serial killer who would invade homes and kill women after stalking them for long periods; other members became unintended victims when they returned home earlier than expected. BTK would later write taunting letters to the media and police about his crimes. Rader's arrest was made possible by metadata found in a floppy disc he sent to police and a partial DNA match to his daughter. Neither technology existed at the time he committed the murders.
Kathryn Bright			April 4, 1974
Lizbeth Wilson	John Henry Horton	Prairie Village, Kansas, USA	July 1974	2003	A 13-year-old girl last seen running across the field of Shawnee Mission East High School by her brother, who was racing ahead of her. Her remains were found in an empty field six months later. Horton became a suspect because he was the only adult working on the school grounds at the time, and the investigation revealed that he had taken a suspicious break and also tried previously to lure other girls into the school. A duffel bag and a bottle of chloroform was found in his car, which Horton claimed using to "get high”, but this was deemed circumstantial. In 2002, investigators interviewed an overlooked 15-year-old girl at the time of the murder who had been given chloroform by Horton and was sexually molested while she was unconscious. However, the Kansas Supreme Court overturned Horton's conviction in 2005 on the basis that the "prior bad act" had not been placed on the public record and the testimony should not have been allowed. A leave to re-try and re-file the case was granted, and this time the same evidence and the testimony of two fellow inmates was enough to declare him guilty.[10]
Katherine and Sheila Lyon	Lloyd Lee Welch	Washington, D.C., USA	March 25, 1975	September 12, 2017	Two sisters aged 10 and 12 who disappeared during a trip to a shopping mall. For decades, the police centered their efforts in locating a 50 to 60 years old man who was seen playing a tape recorder with children in different malls. However, in 2013 the attention shifted to Welch, by then a convicted and incarcerated child molester. Welch, who was 18 in 1975, strongly resembled another man seen stalking the girls by one of their friends, and it was found that in 1975 Welch himself went to the police, claiming that he had seen the older man abducting the girls. After a cousin of Welch confessed to helping him burning two suspicious duffel bags in his property of Thaxton, Virginia in 1975, the police searched the place and found items that had belonged to the girls. While no trace of their bodies was found, Welch pleaded guilty to both counts of abduction and murder.
Myrna Opsahl	Emily and William Harris, Kathleen Ann Soliah, Michael Bortin	Carmichael, California, USA	April 21, 1975	November 7, 2002	A 42-year-old customer killed during the robbery of the Crocker National Bank by the Symbionese Liberation Army. The case was revived only in 1999, after Soliah (indicted for the attempted bombing of two LAPD patrol cars in August 1975) was arrested in Minnesota, thanks to a tip from a neighbor who had watched her case featured in America's Most Wanted.
	James Kilgore			2003	Arrested on November 8, 2002, in South Africa, where he was living under an alias, and extradited to the United States. He was the last SLA member to be apprehended and convicted.
Martha Moxley	Michael Skakel	Greenwich, Connecticut, USA	October 30, 1975	2002	A 15-year-old girl last seen talking to Skakel's brother, Thomas, at a party, and who was bludgeoned and stabbed with a golf club that was traced back to the Skakel home. Over the years, suspicions switched from Thomas to Michael, who was an alcoholic and peeping tom at the time of the murder (when he was also 15) and who was said to have bragged about getting away with murder due to his family's connection to the Kennedys. Skakel was convicted of the murder in 2002, and again on retrial, in 2016.
Carol Hutto	James B. Kuenn	Largo, Florida, USA	December 1976	February 10, 2000	A 16-year-old girl whose body was found in a lake near an abandoned house. She was last seen alive the night before when she received a call. Suspicion fell on her 17-year-old half-brother Jerry Irwin, a known juvenile delinquent who had stayed out all night and whose route home took him past the house and lake.[11] However, the real murderer was Hutto's boyfriend, James B. Kuenn, who later joined the US Navy and served in a submarine. In 1998, Kuenn confessed to NCIS agents that he had killed Hutto and disposed of her body after she refused to have sex with him.[12] Kuenn's confession was confirmed by DNA.
Shirley Vian	Dennis Rader	Wichita, Kansas, USA	March 17, 1977	August 18, 2005	See above.
Nancy Fox			December 8, 1977
Melvin "Ricky" Pittman, Ernest Taylor, Alvin Turner, Randy Johnson, Michael McDowell	Philander Hampton	Newark, New Jersey, USA	August 20, 1978	August 2011	Five African-American teenagers who disappeared at once from Newark's Clinton Avenue. In 2008, while being interrogated for an unrelated case, Hampton confessed to having helped his cousin, local contractor Lee Anthony Evans, in luring the victims to an empty house with the promise of work, then locking them in a room and setting the house ablaze. Hampton led investigators to the place of the fire but no human remains were found. In spite of this, Hampton pleaded guilty and was convicted of five counts of murder, while Evans, who claimed innocence, was acquitted.
Etan Patz	Pedro Hernandez	New York City, New York, USA	May 25, 1979	April 18, 2017	A 6-year-old boy who disappeared on his way to a school stop; his disappearance helped launch the missing child movement and he was the first child with a photo on a milk carton. For decades, suspicion was cast on a convicted child molester, Jose Antonio Ramos. However, Hernandez's brother-in-law identified him as the real perpetrator in 2012, claiming that he had confessed publicly at his church in the 1980s and that his guilt was an open secret in his family. Hernandez confessed again after his arrest, but doubts about his mental health delayed a guilty verdict until 2017.
Floralba Sánchez	Pedro López	El Espinal, Tolima, Colombia	1979	1995	The only identified victim of López, one of the most prolific serial killers of all time, in his native Colombia. López was tried after he completed his controversial 16-year-long sentence in Ecuador and was deported to his home country.[13]

Kalinka Bamberski	Dieter Krombach	Lindau, Bavaria, Germany	July 9, 1982	October 22, 2011	A French 14-year-old girl who died in the home of her German doctor stepfather (Krombach) after being injected with a cobalt-iron solution. Because German authorities declined to prosecute Krombach in spite of his testimony being inconsistent about the purpose of the injection and with the autopsy report, Bamberski's biological father, André, lobbied for Krombach to be prosecuted in France. Krombach was tried in absentia in 1995 and found guilty, but the verdict was annulled by the European Court of Human Rights in 2001. In 2009, Bamberski had Krombach abducted from his home and delivered to a French police station in Alsace, where he was arrested. Krombach was tried again and sentenced to 15 years in prison, while Bamberski received a one-year suspended sentence for his abduction in 2014. Since 1997, several German women have come forward claiming that Krombach drugged and raped them as teenagers.

Elaine Graham	Edmond Jay Marr	Los Angeles, California, USA	March 1983	2005	A 29-year-old nurse and student at California State University at Northridge who was abducted and murdered. Marr became a suspect when he was seen in the immediate area of her disappearance and at a sister's home only a few blocks from where the victim's car was found. Her skeletal remains were found by hikers in a wooded area halfway between where she was last seen alive and where the car was found, some six months later. A knife found in the suspect's possession when he was arrested for armed robbery a month later, was later proven to be the murder weapon when DNA evidence matched blood found in the knife's crevices.[14]

Tiffany Stasi	John Edward Robinson	Overland Park, Kansas, USA	January 9, 1985	October 2002	The four-month-old daughter of a 19-year-old single mother who Robinson met at a battered women's shelter. Robinson promised her a job, home and daycare for the baby in Chicago, and days later gave the baby to his own brother, who had been unable to conceive, under the claim that the mother had committed suicide. Stasi's identity was confirmed by DNA in 2000. Robinson was also convicted for the murder of the mother (whose body was never found), but the conviction was overturned on technicalities in November 2015.[18]
Jonathan Sohus	Christian Gerhartsreiter	San Marino, California, USA	February 1985	August 15, 2013	The neighbor of Gerhartsreiter, a con man. After Sohus and his wife Linda disappeared, Gerhartsreiter told other people that they had moved to Europe, and was later pulled over by police while driving Sohus's car under an alias.

Sherri Rasmussen	Stephanie Lazarus	Van Nuys, California, USA	February 24, 1986	March 2012	A 29-year-old woman killed during a home invasion. The case was classified as a robbery gone wrong until 2009, when DNA from a bite mark on Rasmussen's body was identified as female and detectives reviewing the case determined that the robbery had been staged. The DNA was positively matched to Lazarus, who had had an affair with Rasmussen's husband shortly before she was killed.
Michelle Dorr	Hadden Clark	Silver Spring, Maryland, USA	May 24, 1986	1999	A six-year-old girl who disappeared from her father's backyard while he was taking a nap.

Samantha Knight	Michael Guider	Bondi, New South Wales, Australia	August 19, 1986	August 28, 2002	A nine-year-old girl abducted from her home. Guider, a self-educated expert on Aboriginal sites of the Sydney area, aroused the suspicions of journalists working with him when he made several bizarre statements about Knight. Eventually, Guider confessed to have drugged and molested several girls in New South Wales through the 1980s, with Knight dying from an accidental overdose. Guider also led police to the place he buried Knight; no body was found, likely because the area was altered later for development, but cadaver dogs reacted positively to the site.

Commesso's remains were found in 1995 and identified in 1996. Around the same time, pictures depicting Commesso bound and beaten were found in a truck stolen by Floyd in Oklahoma and abandoned in Texas. Floyd was initially deemed unfit to stand trial on the grounds of mental health, which he denied and fought vigorously. He was subsequently tried and sentenced to death.
Katharine and Robert Baskin	Marvin L. Maple	Murfreesboro, Tennessee, USA	March 10, 1989	c. 2009	Two eight and seven-year-old siblings kidnapped by their grandparents and taken to San Jose, California, where they lived under aliases until they were identified in 2009.

Diane McDermott	John Sponza	Waterbury, Connecticut, USA	February 9, 1967	2012[23]	A 21-year-old woman shot with the gun of her live-in boyfriend, Sponza, who had ties to organized crime. The death was ruled an accident resulting from McDermott picking up the gun while Sponza was cleaning it. However, the case was reinvestigated decades later at the request of McDermott's son, actor Dylan McDermott, and ruled a homicide by Sponza. Sponza was himself murdered in 1972 and his murder remains unsolved.

Muns was officially listed as a thief and a deserter until the NCIS started an investigation at the request of Muns's family, 30 years later. LeBrun, who also worked at the reimbursing office at the time, confessed to being the real thief, to have murdered Muns when he confronted him over it, and to have disposed of the body in one of the ship's tankers. However, he recanted later and the confession was considered not admissible before the court.

The Ransacker escaped and vanished afterward. In 2018, police announced that the Ransacker was also the unidentified serial killer known as the Original Night Stalker, and that his real identity was DeAngelo, who was identified as the Stalker by a DNA match. DeAngelo was a police officer in nearby Exeter during the Ransacker's spree. DeAngelo was charged with Snelling's murder because of undisclosed, non-genetic evidence.
Brian and Katie Maggiore		Rancho Cordova, California, USA	February 2, 1978		A young couple chased and fatally shot while walking their dog at night.

April 6, 1981	April 2015	A 20-year-old woman last seen alive when she left her family home in the company of Kalhauser, her boyfriend, in 1980. Her body was discovered in Arizona in 1981 and remained unidentified for 34 years, during which she was known as the "Pima County Jane Doe". In 1995, a photograph of Gerow while she was still alive surfaced in the possession of Kalhauser, who was pending trial for the murder of his wife, Diane Van Reeth. Police announced that they believed the photograph to be connected to the unidentified decedent in 2014 and confirmed this when they matched the body's DNA to Gerow's family.
Adam Walsh	Ottis Toole	Hollywood, Florida, USA	July 27, 1981	December 16, 2008	A six-year-old boy abducted from a department store; only his head, severed post-mortem, was found two weeks later. Though Toole confessed to the murder already in 1983, the fact that he and his sometimes associate Henry Lee Lucas made false confessions to several other murders cast doubt on his testimony, and he eventually recanted. The prosecution was further complicated when police lost Toole's car and a machete before proper testing could be done. Nevertheless, the police and Walsh's family made a joint announcement in 2008 about their confidence in Toole's guilt based on circumstantial evidence. The investigation of Walsh's murder was then officially closed. Among the evidence was Toole's niece's claim that he had again confessed the murder and decapitation of Walsh while on his deathbed in 1996, seemingly unprompted.
Tina Harmon	Robert Anthony Buell	Lodi, Ohio, USA	October 29, 1981	2010	A 12-year-old girl who was abducted, raped and murdered. A man was convicted for her murder in 1982 but released after winning a retrial in 1983. In 2010, DNA found at the murder scene was matched to Buell, who had been executed in 2002 for the 1982 murder of Krista Harrison. Further matches were made between fibers found on Harmon and Harrison's bodies, and between dog hair found on Harmon and a dog buried in Buell's yard.

Her bones were found at the bottom of a cliff by a ginseng hunter in 2003 and identified by the FBI five years later. Because of the lack of foul play evidence, the death was ruled accidental.
Hashimoto (first name unknown)	Miyoko Sumida	Amagasaki, Hyōgo, Japan	1987	November 2011	Believed to be the first victim of the Amagasaki Serial Murder Incident discovered in 2011. The victim, the mother of later victim Jiro Hashimoto, disappeared when she and Sumida were in their 30s.

However, a genealogical DNA test in 2013 revealed that the source of the semen was a man of North African extraction, who was later identified as Chelh, a Moroccan immigrant who had moved to France in 1999. Chelh was arrested and extradited in 2015, but he committed suicide while awaiting trial on January 29, 2016. The investigation was formally closed the following month.
Natascha Kampusch	Wolfgang Přiklopil	Vienna, Austria	March 2, 1998	August 23, 2006	A 10-year-old girl who was abducted on her way to school and held in captivity until she escaped, eight years later. Přiklopil jumped in front of a train when he learned of Kampusch's escape.
Danny, Kathy and Ashley Freeman, Lauria Bible	Ronnie Busick, Phil Welch, David Pennington	Welch, Oklahoma, USA	December 29–30, 1999	April 26, 2018	Married couple Danny and Kathy were murdered in their home, later set on fire, while their teenage daughter (Ashley) and her friend (Lauria) disappeared. Lauria's car and keys were at the scene, evidence that she had been there before vanishing. Two decades later, it was announced that Busick and his friends Welch (d. 2007) and Pennington (d. 2015) had bragged repeatedly about murdering the Freemans over drug debts, then taken the girls to a trailer home, where they raped and murdered before disposing of the bodies in a mineshaft. Busick was charged with all four murders and is pending trial.

2000s

Victim(s)	Suspect	Location	Crime date	Breakthrough date	Description
Zebb Quinn	Robert Jason Owens	Asheville, North Carolina, USA	January 2, 2000	July 10, 2017	An 18-year-old Walmart employee who disappeared after his daily shift, when he went to buy a car with Owens, a coworker. Owens was one of two primary suspects until 2015 when he was arrested for the unrelated murder of Cristie Schoen Codd and her husband. In 2017 he was convicted of the Codds murders and indicted for Quinn's murder; the reasons for the latter are undisclosed.
Chandra Levy	Ingmar Guandique	Washington, D.C., USA	May 1, 2001	March 3, 2009	A Federal Bureau of Prisons intern who disappeared and was found murdered in Rock Creek Park over a year later. Police and media centered their attention on US Congressman Gary Condit, whom she had an extra-marital affair with, until eight years later when an investigation by The Washington Post led to Guandique, a Salvadoran illegal immigrant incarcerated for assaulting two other women in the same place around the time of Levy's murder. Guandique was convicted of the crime in 2011, but the conviction was overturned and a retrial was called in 2015 after it was determined that a witness at the first trial had committed perjury. On July 28, 2016, prosecutors announced that they would no longer seek charges against Guandique and instead worked to have him deported.
Joseph Curseen, Thomas Morris Jr., Ottilie Lundgren, Robert Stevens, Katherine Nguyen (plus 17 others injured)	Bruce Edwards Ivins	Boca Raton, Florida and Washington, D.C., USA (also injured in New York City)	September 18 - October 9, 2001	August 6, 2008	Random people mailed letters infected with anthrax in the aftermath of the September 11 terrorist attacks. Early investigations focused on biological weapons expert Steven Hatfill but shifted to Ivins after the viral strain was identified as coming from his lab. Ivins committed suicide on July 21, 2008, when the FBI was about to lay charges on him, and he was named the official perpetrator a week later. The investigation was formally closed on February 19, 2010.
Takashi Tanimoto, Hisayoshi Sumida	Miyoko Sumida and her family	Hyōgo and Okinawa, Japan	2003 - 2005	November 2011	Victims in the Amagasaki Serial Murder Incident and relatives of Sumida, who may have killed them for insurance. Like in the other murders, Sumida admitted them after her arrest and produced a written chronicle of her crimes, then committed suicide while in police custody.
Tara Grinstead	Ryan Alexander Duke, Bo Dukes	Ocilla, Georgia, USA	October 23, 2005	2017	A high school history teacher who vanished from her home. Though no body was found, Duke and Dukes (no relation), two former students at the high school, were respectively charged with murder and concealment.
