SAN ANTONIO -- A 14-year-old girl who was shot by federal drug agents remained on life support Tuesday at Wilford Hall Medical Center.

Ashley Villarreal (pictured, left) suffered a gunshot wound to the head after Drug Enforcement Administration officers fired four rounds toward a car the teenager was driving, officials said.

The shooting occurred late Sunday night during surveillance of the girl's home in the 800 block of San Joaquin.

Officials said plain-clothed DEA officers were trying to apprehend the girl's father when the teenager and another man, described as a caretaker for the girl's grandmother, got into a car and started to drive away.

The federal agents said when they tried to stop the pair, the girl, who was driving, drove the car toward the agents. Officials said that's when the agents opened fire.

"It looked like a gang (shootout)," said Kayla Hernandez, a neighbor who watched the incident from her home. "Those narcs and the DEA didn't put on their jackets until after the cops got here."

But Adriana Martinez, a neighbor, said the agents were well identified.

"When I checked outside ... they already had the jackets on," Martinez said.

Family and friends said that Villarreal got into the vehicle to park it when she apparently panicked and was unaware it was DEA agents who were trying to stop her.

The San Antonio Police Department is handling the shooting aspect of the incident.

The shooting was the second incident involving gunfire for the DEA in San Antonio in the past four months.
