Tucson police are looking for witnesses to a homicide that took place Friday night at theΒ Ronstadt Transit Center.

Tucson police have identified a man who was stabbed to death overnight at the Ronstadt Center in downtown.

Joseph Robert Lundberg, 38, died as emergency workers tried to save his life about 12:30 a.m. Saturday.

Tucson fire crews and Tucson police went to the transit center, after a 911 caller reported a wounded man, said Sgt. Pete Dugan, a department spokesman.

Officers found Lundberg near a bus bench with obvious signs of trauma. Tucson fire paramedics immediately began to perform first aid, however the man was pronounced dead at the scene, Dugan said.

Homicide detectives have since learned that Lundberg was stabbed during a fight with a man about 11:30 p.m. near the center's bus benches. The man who stabbed Lundberg ran away, heading north away from the center, Dugan said.

Detectives say other people were in the area at the time of the stabbing and have seen the brawl. Anyone with information is asked to call 911, or 88-CRIME, the anonymous tipster line.
