JEFFERSON COUNTY, Colo. -- Recently discovered evidence suggests a man missing since January might have been killed, the Jefferson County Sheriff's Office said Thursday.
Joseph Brinson, 28, was reported missing on Jan. 23. He was last seen at his home in the 9000 block of Mica Mine Gulch Road on Jan. 17.
"During the investigation, investigators were able to obtain some forensic evidence which leads them to believe that a crime occurred in this case," said Jefferson County Sheriff's office spokesperson Mike Taplin.
Investigators did not provide specifics on what the new evidence is that led them to believe foul play might be involved.
FOX31 and Channel 2 learned three people were seen at his home around the time he disappeared. They were standing at a door not normally used. A gunshot was heard about the time he disappeared, and a black BMW was seen in the area.
Neighbors say Brinson and a roommate had been renting the home for about three months.
Anyone with information is asked to call the sheriff's office at 303-271-5612 or Metro Denver Crime Stoppers at 720-913-7867.
