A passerby found a body with “obvious signs of trauma” in a south side park Saturday morning, a police official said.

Police were called at about 7:45 a.m. after the man was found dead in a grassy area of El Pueblo Park at 101 W. Irvington Road near South Sixth Avenue, Sgt. Chris Widmer, spokesman for the Tucson Police Department, said in a news release.

Detectives spent much of the day canvassing the area for evidence and speaking with neighbors.

Anyone with information should call 911 or 88-CRIME.
