DEMING, N.M. (AP) _ A 13-year-old girl who police said had been shot in the head by a fellow student at a New Mexico school died Saturday.

Araceli Tena died at Thomason Hospital in El Paso, Texas, where she'd been rushed by ambulance Friday shortly after she was shot in the lobby of Deming Middle School, police said.

Victor Cordova Jr., 12, of Palomas, Mexico, was wearing a camouflage jacket when he fired a single shot from a .22-caliber handgun, police said.

Carlos Viramontes, Deming schools superintendent, said Saturday police were trying to determine a motive for the shooting at the only middle school in this farming and ranching town of 15,000, about 33 miles north of the Mexican border.

Cordova had been charged with attempted murder, assault, aggravated assault and aggravated battery Friday.

Investigators will be working with prosecutors to amend the charges, said police.

The school district had established a safety plan for such an incident following the fatal shootings at Columbine High School in Littleton, Colo., Viramontes said.
