TULSA, Oklahoma - Tulsa Police issued more information in the city's latest murder. They are searching for a suspect who killed Aaron Armstrong overnight Saturday.

Armstrong, 18, was found shot to death in the parking lot of the QuikTrip at 47th and Yale just after midnight September 12. 

Homicide Sergeant David Walker said people in two vehicles - a white Chevrolet Impala and gray Chevrolet Camaro - met in the parking lot of the convenience store.  Two of the people in each car exchange positions, getting into the other vehicle, Walker said in a news release. Both cars started to leave the parking lot.

Instead of leaving, however, both cars stopped again in the lot. Armstrong and another man were walking on Yale and approached the Impala, the release states. Both men got in the car very briefly and then got back out.

The driver of the Camaro got out of that car and shot Armstrong, according to police. A passenger in the Impala then got into the Camaro which drove off. The driver of the Impala got out and walked away, leaving that car in the QT lot.

The man who was walking with Armstrong ran south from the murder scene, Walker said.

"Homicide detectives, fugitive warrant officers Muskogee police officers, Muskogee County Sheriff’s Deputies and the U.S. Marshal’s Service spent the day locating the Camaro and those that failed to cooperate that were in the Impala and Camaro," Walker said in the release. The Camaro was found in Muskogee.

Investigators also interviewed several people in Tulsa, finding an apartment used by some of the people involved.

"We believe we know the identities of those involved and are working to locate and interview them about this murder," Walker said. "Anyone with information on this murder please call Crime Stoppers at 918-596-COPS, the Homicide Tip Line at 918 798 8477 or email homicide@cityoftulsa.org.
