SAN ANTONIO, Texas — San Antonio Police have released images of a suspect who they said shot and killed a San Antonio convenience store clerk earlier this month and are hoping someone will step forward to identify him.

Timothy Collins, 42, worked at a 7-Eleven at 7930 Callaghan Road near I-10 on the city's northwest side. He was transported to University Hospital after being shot on January 1, where he later died.

Kyle Shane of Kerrville stopped at the 7-Eleven just before the shooting. He was in San Antonio celebrating New Year’s Eve with friends. He said a store clerk was mopping when he was shot.

Shane, 31, also said before the shooting, he asked the suspect for directions and said he was parked outside the convenience store in a Chevy Trailblazer.

“He was waiting for us to leave, you could just tell,” he said. “Man, this is my 7-Eleven. I came here every day. I used to live in the apartment complex next door."

If you know the man in the surveillance images or have information about the incident, you are asked to call the San Antonio Police Department’s Public Information Office at 210-207-7579.

A $15,000 is being offered for information leading to the suspect's arrest.
