DECATUR, Tex. — Sources tell FOX31 Denver that government officials continue to look into a possible connection between the arrest of Saudi national Homaidan Al-Turki as a  motive in the murder of Department of Corrections Executive Director Tom Clements.

However, investigators admit they are beginning to “deprioritize” the theory.

Homaidan Al-Turki was convicted in 2006 of unlawful sexual contact by use of force and other charges. Prosecutors said he sexually assaulted a housekeeper and kept her as a virtual slave for four years.

Federal sources tell FOX31 Denver agents were having trouble contacting al-Turki after his housekeeper’s visa expired.  The source could only speak anonymously because they were not authorized to speak publicly about the case.

The source told FOX31 Denver reporter Justin Joseph investigators tried to speak with al-Turki for months but he refused to answer his front door.

An agent devised a scheme to dress as a pizza delivery man which tricked al-Turki to open his door. When he did, agents searched his home and found his housekeeper in the basement, the source said.

Al-Turki was eventually convicted for the crime.. Recently he sought permission to serve his sentence in Saudi Arabia.

Clements denied the request and was murdered at his front door eight days later.

Sources tell FOX31 Denver in the suspect’s car they found a pizza delivery uniform which sources believe may have been used as a disguise to coax Clements to open his door.

Late Friday, a different high-placed law enforcement source discounted the al-Turki connection to the Clements murder.
