Saudi prisoner investigated in prison chief Tom Clements' death DENVER, April 30 (UPI) -- Police in Colorado said a Saudi may have been involved in the slaying of prisons chief Tom Clements, who had denied the man's petition to be sent back home. FBI investigators have interviewed Homaidan al-Turki, a Saudi national serving eight years to life at Limon Correctional facility, as well as his associates, The Denver Post reported Monday. Al-Turki is in prison for keeping a housekeeper as a virtual slave and sexually assaulting her. Investigators are looking at possible financial transactions between al-Turki and members of white supremacist gang 211 Crew, of which Evan Ebel, the main suspect in Clements' killing, was a member, the newspaper said. Police are investigating whether al-Turki paid the 211 Crew to protect him. A source told the Post al-Turki "has tons of money" he transfers "from account to account" through operatives outside the prison. Investigators are also examining commissary records and phone conversations. Al-Turki's lawyer, Hal Haddon, said the suggestion his client was involved in the death of Clements is "outrageous." "He's been in prison seven years," Haddon said. He is not a man of great means. He was a Ph.D. candidate at the University of Colorado. Al-Turki's legal team filed a lawsuit April 8 in Denver District Court saying the Saudi man had been isolated and mistreated in prison since Clements' death.
