Jurors in the trial of Michael Clark started deliberating Thursday and were due to resume deliberations Friday.
Clark is charged with first-degree murder in the death of Marty Grisham, who was shot after answering a knock at the door on Nov. 1, 1994.
Clark was friends with Grisham's daughter and pleaded guilty at the time to theft and forgery for stealing and using Grisham's checks.
He has denied killing Grisham. The Daily Camera reports that in closing trial arguments, a prosecutor said Clark is the only person who had the motive and means to kill Grisham.
Clark's lawyer says police haven't found concrete evidence.
