BRIGHTON |  A judge has determined that prosecutors have enough evidence to try a Colorado man for murder in the shooting death of a sheriff’s deputy.

Dreion Dearing, who is 22, faces multiple first-degree murder charges in the death of Adams County Sheriff’s Deputy Heath Gumm.

Prosecutors said Monday that forensic testing found Dearing’s blood on a pistol found near the shooting location and shoeprints similar to Dearing’s shoes.

Dearing’s attorneys questioned the validity of a photo lineup linking Dearing to the initial report of a fight.

Police have said that Gumm and other deputies were called to a residential area north of Denver on Jan. 24 for a reported fight and chased a man who ran behind the house. They said the man pulled out a handgun and fired.
