Rakhat Aliev, a former son-in-law of the Kazakh president turned prominent government critic, was found dead in a jail in Vienna on February 24. Aliev was being held on murder charges, which he had dismissed as politically motivated. Austrian authorities have said his death appears to be a suicide, but Aliev's lawyer has voiced doubts and called for a "very thorough" investigation. Here are some photographs from a life full of controversy.
