In the latest shooting, a man was parking his truck and about to exit his vehicle at Gulfgate Center when a gunman approached and tried to rob him about 10 p.m., said Sgt. Robert Odom, an HPD homicide detective. The intended victim grabbed his own gun, shooting and killing the suspect. "It appears at this time this time the (robbery) victim was acting in self defense," said HPD spokesman John Cannon. The shooter had a concealed weapon permit, Odom said. The case will be referred to the Harris County District Attorney's Office for review. Investigators were interviewing witnesses and another possible suspect, who was taken into custody late Wednesday. In the earlier shooting, two teenagers were killed and a third suffered gunshot wounds in a drive-by shooting near a Randalls in southwest Houston. The triple drive-by shooting was reported about 6:30 p.m. after a blue four-door sedan riddled with bullet holes pulled into the parking lot of a shopping center in the 4800 block of West Bellfort near South Post Oak. A youth in his early teens was found dead in the front passenger seat of the car, said Sgt. E.B. Cisneros of HPD's homicide division. He had three gunshot wounds to his back. The car's driver and a back seat passenger were taken to the hospital, Cisneros said. One died at the hospital overnight. He had a gunshot wound to his head. The other is expected to live. Names of the victims have not been released. Investigators believe the shootings took place elsewhere and that the wounded driver drove his badly injured passengers to the shopping center, which includes a Randalls store, a Starbucks and a Chili's. "We are still looking for help from witnesses," said HPD's Cannon. "As of now, there are no witnesses or suspects." Investigators say a black, 4-door Honda might have been linked to the shootings. A Randalls employee who asked not to be identified said she didn't hear shots when the car pulled into the lot, but she saw a man open one of the car's doors and stumble to the ground before bystanders called police. "It looks like the shots were fired elsewhere and these guys drove to this parking lot to summon help," Cannon said. "We're still waiting for statements from the surviving victim." Police ask that anyone with information about these shootings call HPD's homicide division at 713-308-3600 or Crime Stoppers at 713-222-TIPS.
