Direct answer: The Tajikistan archive currently contains one adjudicated case: the 29 July 2018 attack on a group of touring cyclists in Danghara District. Jay Austin, Lauren Geoghegan, René Wokke and Markus Hummel were killed. Tajikistan's Supreme Court later sentenced Hussein Abdusamadov to life imprisonment and imposed prison terms on other defendants. The archive classifies the criminal case as solved or adjudicated, while separately preserving concerns about the closed trial and competing claims over which organization directed the attack.

Cases appear here only after a documented judgment establishes criminal responsibility. The archive still records procedural limits and unresolved attribution questions.
Documented cases in which no judgment has established criminal responsibility or the perpetrator remains unidentified.
The solved label rests on convictions and sentences reported by the Supreme Court and multiple established news organizations, not on the initial arrest or public claims of responsibility.
Islamic State claimed the attack and released a pledge video. Tajik authorities instead blamed people linked to the banned IRPT, whose leadership denied involvement. The archive does not collapse those competing claims into a single proven fact.
The proceedings were not open to journalists, diplomats or relatives. That restriction matters when assessing how independently the evidence and organizational allegations could be scrutinized.
One fully sourced case file is published: the 2018 Danghara cyclist attack and the closed Supreme Court trial that followed.
It is classified as solved or adjudicated because Hussein Abdusamadov was convicted and sentenced to life, while other defendants received prison terms. The label does not treat disputed organizational-attribution claims as settled fact.
The four people killed were Jay Austin and Lauren Geoghegan of the United States, René Wokke of the Netherlands and Markus Hummel of Switzerland.
The proceedings were held in a detention facility without public access. Reporting said journalists, diplomats and relatives were excluded, an important limitation on independent scrutiny of the case.
No single organizational attribution is presented as conclusively established. Islamic State claimed responsibility and released a pledge video; Tajik authorities blamed people linked to the banned IRPT, whose leadership denied involvement.
