TULSA, Oklahoma - A shooting victim died after being dumped at a Tulsa hospital Wednesday afternoon, and police are now searching for the car that dropped him off.

Tulsa Police Sergeant Dave Walker said a couple of attempts were made to revive the victim, but he died at St. Francis hospital after being left there around 1:15 p.m.

Walker said witnesses described the vehicle that dropped the victim off as a light-colored Lincoln Continental or Grand Marquis. That car didn't stay at the hospital.

The victim's identity has not yet been released. Police say his death is the city's 32nd homicide of 2013.

Investigators say they found blood and shell casings on a sidewalk at River Glen Apartments, near 62nd and Peoria, and they're surmising that's where the shooting took place.

Through canvassing witnesses at the apartment complex, police say they determined they needed to look inside a particular apartment.

Police have found a black Mustang they were looking for that witnesses said left the complex after the disturbance. Walker said they've spoken with the occupants of that car and released them.

They've also located two people they were looking for in connection with the shooting.

Investigators say they don't yet have enough evidence to support arresting anyone.

Right now, police are looking for the vehicle that dropped the victim off at St. Francis and the people that were in that car.

Anyone with information is asked to call Crime Stoppers at 918-596-COPS or the Homicide Tip Line at 918-798-8477.
