Houston police are searching for the gunmen responsible for a shooting outside a southwest-side shopping center on Wednesday that sent three young people to the hospital.

The victims, an 11-year-old girl and two boys, believed to be about 15 or 16, were shot about 4 p.m. in the 5800 block of Renwick. They were taken to area hospitals with what Houston police said were non life-threatening injuries. The girl was shot in the arm while the two boys were shot in the foot and the leg.

The motive remains under investigation, but an officer identified the two boys as gang members. Police have not been able to locate anyone who actually saw what happened.

"There were people who heard gunshots," said John Cannon, a Houston police spokesman. "They (the investigators) believe more than one suspect fired shots."

Police were checking whether any security cameras in the vicinity might have captured the shooting.
The shopping center is adjacent to an apartment complex. Although the apartments are surrounded by a fence, there is easy access through a gate.

A teenager who identified himself only as "Luis" said he knows all three shooting victims and spoke to them. He said they were shot on the grounds of the apartment complex then helped each other get through the gate and onto the shopping center parking lot where they fell. He was later questioned by HPD investigators.

A Houston police officer at the scene said the two teenage boys were "documented" members of the MS-13 street gang. The girl has no known gang involvement, the HPD officer said, and was simply with them when the assailants drove up and opened fire.

MS-13 or Mara Salvatrucha is a transnational criminal gang with most of its members coming from Central America. The gang has a reputation for extreme violence.
