Unterweger was extradited back to Austria on 27 May 1992, and charged with 11 murders, including one in Prague and three in Los Angeles. The jury found him guilty of nine murders by a 6:2 majority (sufficient for a conviction under Austrian law at the time). Based on psychiatric examination, Austrian psychiatrist Dr. Reinhard Haller diagnosed Unterweger with narcissistic personality disorder and presented his findings to the court on 20 June 1994. On 29 June 1994, he was sentenced to life in prison without possibility of parole.
