AUSTIN (KXAN) — Police arrested a suspect in the murder of a middle-aged man that took place Wednesday morning at a popular Austin park.

Police said a passerby called 911 just before 7 a.m. after finding an unresponsive man lying in a part of Auditorium Shores park near West Riverside Drive. When they arrived, officers said they noticed the man was bleeding from trauma to his head. He was pronounced dead by EMS shortly thereafter.

Police arrested Coltan Moore, 30, on a first-degree murder charge. They said Moore “brutally assaulted” the victim using large rocks, causing fatal injuries.

Police said they believe the homicide may have happened sometime after 2 a.m. Wednesday, so they’re asking anyone who may have seen something at that time in the park to contact the Austin Police Department.

People can pass along details by calling Crime Stoppers at (512) 472-TIPS or the APD homicide unit’s tip line at (512) 477-3588.

Police added they believe this is an isolated incident, and there is no threat to the public. APD said parts of the park would be closed Wednesday due to the investigation.

Officer Michael Bullock with APD’s Public Information Office said homicides in this area don’t usually happen.

“I’ve personally worked this sector for approximately five years now, and it’s very uncommon for us to have an incident in this public of a place,” Bullock said.

He explained there used to be a parks unit within APD that would patrol these areas regularly in the early morning, but that unit has now been disbanded because of strained staffing.

Although the homicide on Aug. 25 at Zilker Park and this homicide are isolated incidents, APD will be increasing patrols in all city parks to help deter violent crimes.
