This '''list of unsolved deaths''' includes notable cases where:
* The [[cause of death]] could not be officially determined following an investigation
* The person's identity could not be established after they were found dead
* The cause is known, but the [[manner of death]] (homicide, suicide, accident) could not be determined following an investigation
* Different official investigations have come to different conclusions

Cases where there are unofficial alternative theories about deaths – the most common theory being that the death was a homicide – can be found under: [[:Category:Death conspiracy theories|Death conspiracy theories]].

===Medieval===
* [[Princess Yongtai]] (15–16), 701. In both the [[Old Book of Tang]] and [[New Book of Tang]], it is recorded that she was executed by [[Empress Wu Zetian]] with her brother and husband because of talking about rumors about the two officials [[Zhang Yizhi and Zhang Changzong]], who were also the lovers of Empress Wu Zetian. However, from her epitaph, it was said she was pregnant when she died. From a piece of her pelvic bone, it has been presumed that she died from childbirth, because her pelvis seems to be smaller than other women at the same age. It is also suspected that she went into shock on hearing the news that her brother and husband had been executed, and it caused a fatal miscarriage.

* [[Meriwether Lewis]] (35), an American explorer who helped explore territory bought during the [[Louisiana Purchase]], was found dead with multiple gunshot wounds in an inn along the Natchez Trace, a nature trail in Tennessee, in 1809.

The reported location of the woman's death, Room 8 at [[Gadsby's Tavern]], is also a tourist destination, and supposedly her ghostly visage can be seen standing at the window.
* [[Paul Johann Anselm Ritter von Feuerbach]] (57), a German legal scholar, died on 29 May 1833. The circumstances remain unclear – his family as well as he himself shortly before his death believed that he had been poisoned due to his protection of and research work on [[Kaspar Hauser]], who himself died the same year under suspicious circumstances (see below).<ref>{{Cite web|url=https://www.lto.de/recht/feuilleton/f/zum-todestag-von-johann-paul-anselm-ritter-von-feuerbach-kriminalpsychologie-straftat-kaspar-hauser/|title=Zum Todestag von Johann Paul Anselm Ritter von Feuerbach: Der Kriminalpsychologe, der den Fall Kaspar Hauser nicht überlebte|last=LTO|website=Legal Tribune Online|language=de|access-date=2019-08-06}}</ref>

On 14 December 1833, he came home with a deep stab wound in his chest of which he died three days later. While he had claimed to have been attacked, the court of enquiry doubted this due to inconsistencies in his claims and speculated that he wounded himself in order to seek attention and revive the fading public interest in him, a theory that is also supported by some historians today.

The New Zealand police believed instead that the methanol had been "unknowingly" introduced into Marks' system but could not conclusively call the case a homicide. Further investigation has been frustrated by the refusal of American agencies to share their findings, the global dispersal of researchers and personnel at the base that winter, the 2006 disappearance of the doctor who treated Marks, and the loss of any possible crime-scene evidence during the winter after Marks' death.

* [[Death of Jeremiah Duggan|Jeremiah Duggan]] (22), a British student studying in [[Paris]], was found dead on a highway in [[Wiesbaden]], Germany, early on 27 March 2003. The initial investigation concluded he had died by suicide by running into traffic. However, his mother, noting that he had called her in great distress over his involvement with the [[LaRouche movement]], who may have discovered that he was British and Jewish, within an hour of his death, never accepted that theory, and a later investigation found evidence that the accident may have been staged to cover an earlier beating. The case was reopened in 2012 after extensive litigation in England, resulting in a change of the cause of death to "unexplained", with the note that Duggan may have been involved in some sort of "altercation" beforehand.<ref>Varney, Merry.

* [[Jürgen Möllemann]] (57), German [[Free Democratic Party (Germany)|Free Democratic Party]] politician, died on 5 June 2003 in a [[parachuting]] incident at [[Marl, Germany|Marl-Lohmühle]]. His death was investigated by the Essen district attorney's office, which published a final report on 9 July 2003. While outside interference was ruled out, no definite verdict was reached on whether Möllemann died by [[suicide]] or had [[death by misadventure|died via misadventure]].<ref>{{Cite web|url=http://www.mopo.de/news/parteien-ermittler--keine-neuen-erkenntnisse-durch-moellemann-video,5066732,5557624.html|title=Ermittler: Keine neuen Erkenntnisse durch Möllemann-Video|publisher=Hamburger Morgenpost|date=29 June 2007|access-date=3 June 2013|archive-date=11 July 2013|archive-url=https://web.archive.org/web/20130711014653/http://www.mopo.de/news/parteien-ermittler--keine-neuen-erkenntnisse-durch-moellemann-video,5066732,5557624.html|url-status=dead}}</ref> Shortly before his death, Möllemann, a passionate and experienced skydiver, had been confronted with allegations he had been involved in illegal arms deals and evaded taxes on millions of euros he allegedly earned from these activities.

The tax evasion charges were dropped after his death.
* Singer-songwriter [[Elliott Smith]] (34) died of stab wounds inflicted in his [[Los Angeles]] home on 21 October 2003. His girlfriend, Jennifer Chiba, claims she got out of the shower after an argument—having heard him scream—to find him with a knife sticking out of his chest, and found a short suicide note on a [[Post-it note|Post-It]] shortly thereafter. Despite common belief, the note did not misspell Elliott's name by leaving out a 't'; it was instead the coroner who made the mistake on the report. While he did indeed have a history of [[Depression (mood)|depression]] and [[Addiction|drug addiction]], friends say [[From a Basement on the Hill|he was actively working to finish an album at the time and seemed optimistic.]] The coroner found the stab wounds were inconsistent with a [[suicide]] attempt but could not conclude it was a [[homicide]] either; the cause of the stabbing remains undetermined and has not been further investigated.<ref>{{cite web |url=http://www.thesmokinggun.com/documents/crime/rockers-autopsy-doesnt-rule-out-homicide |title=Rocker's Autopsy Doesn't Rule Out Homicide |date=2004-01-08 |website=The Smoking Gun |access-date=2017-05-18}}</ref>

The FBI, which has jurisdiction over the possible murder of any U.S. federal employee, found that Luna had mounting financial problems and was facing an investigation over missing money at his office; they considered it a suicide or botched attempt at staging a kidnapping. However, the [[Lancaster County, Pennsylvania|Lancaster County]] coroner's office, pointing to evidence suggesting he had been abducted and someone else was driving for at least the final stage of his drive, ruled it a homicide and considers the case open.<ref>{{cite news|last=Hewitt|first=Bill|title=Who Killed Jonathan Luna?|url=http://www.people.com/people/archive/article/0,,20149007,00.html|newspaper=[[People (magazine)|People]] |date=2003-12-22 |access-date=2014-11-11}}</ref>

Many of his friends and family suspected homicide as he had complained of someone following him in his efforts to stop the auction of a cache of Doyle's personal papers that he believed to have been wrongfully acquired. However, despite suicide by garrotte being unusual and difficult, some investigators believed that he had followed the example of one of Doyle's [[Sherlock Holmes]] stories in which a woman stages her suicide to look like a murder.

British officials who were allowed to examine the body disputed that conclusion, saying they saw no evidence of choking or [[blunt force trauma]]; Dubai authorities have declined repeated requests to share evidence such as CCTV footage from the original incident and the police station that might clarify matters. A coroner's inquest in the UK that considered only the autopsy report and the diplomats' reports returned an open verdict.<ref>{{cite web|url=https://www.independent.co.uk/news/world/middle-east/fresh-doubts-over-briton-lee-bradley-brown-s-death-dubai-8595547.html|title=Fresh doubts over Briton Lee Bradley Brown's death in Dubai |date=2013-04-29 |website=The Independent}}</ref>

The two had last been seen alive on 1 April when they went for a hike on the popular El Pianista trail. After unsuccessful initial searches, a backpack belonging to the women was turned in by a local. It contained their phones, a Canon camera, and personal effects. After two months, a small fraction of their remains was found as well. The women's cell phones showed that they had repeatedly attempted to contact emergency numbers shortly after taking pictures of themselves at the [[Continental Divide]]. Those calls had continued over several days, and Froon's camera contained 90 photographs taken in the night of 8 April, seven days after their disappearance. Most of the photos showed the jungle in the dark, but some of them contained rock formations, small pieces of paper and other items in close-up, and one contained the back of Kremers' head. It was impossible to determine from the remains that were found exactly how they had died. Local officials believe the women suffered an accidental injury shortly after getting lost in a network of trails in the region's [[cloud forest]]s and got lost in the wilderness around [[Volcán Barú]]; however, Panamanian lawyers for their families have pointed to failings of the investigation and suggested both women could have met with foul play.<ref>{{cite web|url=http://www.thedailybeast.com/articles/2016/08/21/the-lost-girls-of-panama-the-full-story.html|title=The Lost Girls of Panama: The Full Story|date=21 August 2016|publisher=The Daily Beast|first=Jeremy|last=Kryt}}</ref>
