An accountant for the Fox network TV show "Prison Break" was found dead at the landmark Drake Hotel, authorities said Tuesday.

Matthew Houbrick, 42, of Calabasas, Calif., was found Monday lying on the floor of his hotel room unresponsive and with no pulse, Chicago Police spokesman Pat Camden said Tuesday. Police officers observed white powder and white pills on a table in the room, he said.

Houbrick was pronounced dead at 8:50 p.m. Monday by Cook County Chief Medical Examiner Edmond Donoghue. An autopsy was scheduled for Tuesday.

"Prison Break" is a drama about a man trying to break his wrongfully convicted brother out of prison. It is filmed in part at the Joliet Correctional Center southwest of Chicago.

"We are saddened by the passing of Matthew Houbrick, who served as an accountant on our production of the television series 'Prison Break,'" Fox said in a statement. "Our deepest condolences go out to his family during this difficult time."

Houbrick previously worked as a production accountant on "7th Heaven," "Pacific Palisades" and "The Love Boat: The Next Wave." He served as a production supervisor on the WB series "Charmed" from 1999 to 2000.
