Deshone Marquez-Jones was 24 when he was shot in the head in Denver in the early morning hours of Sunday, September 18, 2011. He and three friends had been celebrating at the Rockstar Lounge near 10th Avenue and Lincoln Street and, while walking to their car, became involved in an argument with a large group of 20 to 30 men near 9th and Lincoln. The dispute escalated into a physical confrontation in a parking lot and then a pursuit down an alley; as the men neared Marquez-Jones’s vehicle, a single gunshot struck him.

He was taken to a hospital in critical condition and pronounced dead after his family removed life support at about 11:45 a.m. that same day. Two people were arrested immediately after the shooting but later released, and investigators say the size of the crowd suggests there were likely many witnesses. Marquez-Jones was a father to a 10-month-old daughter and was working two jobs to support his family. His homicide remains unsolved and is being treated as a cold case.

If anyone who was in that area on September 18, 2011 has information that could help identify the shooter or those responsible, please come forward.
