AURORA | Arapahoe County Sheriff officials are asking the public for information about a lethal shooting at Cherry Creek State Park Sunday evening that is now a homicide investigation.

Investigators said the shooting occurred at about 7:30 p.m. near the west boat ramp inside the park, and that deputies were called to assist park rangers after the incident.

One adult victim was rushed to a nearby undisclosed hospital and died from gunshot wounds Monday, officials said. Sheriff officials would not release any identifying information about the shooting victim.

The Arapahoe County Coroner’s Office identified the slain man as Jackson Lee Chavez, 26. Chavez died of gunshot wounds to the chest and abdomen and his death was a homicide, the coroner said in a statement.

The gunman left the area after the shooting but is still at large. Officials would not release information about the shooter.

Julie Brooks, a spokeswoman for the sheriff’s office, said sheriff’s deputies are leading the investigation and working with rangers from Colorado Parks and Wildlife.

The west boat ramp in the park was closed for much of Monday but has since reopened.

Anyone with information about the shooting is asked to contact the Arapahoe County Sheriff’s Office at 303-795-4711.
