The Daily Camera reported that prosecutors formally filed the charge Thursday against Michael Clark, who is being held without bond in Boulder County in the death of Marty Grisham.

Grisham was shot four times in the head and chest after answering a knock at his apartment door on the evening of Nov. 1, 1994.

Clark had pleaded guilty to stealing and forging checks from Grisham, who had reported the theft around the time he died. Clark denied involvement in Grisham's death, but he was arrested this month after investigators reopened the case.

A bond hearing for Clark is scheduled for Jan. 19. A preliminary hearing at which prosecutors must show they have enough evidence to justify going to trial is set for April 5.
