Miami Herald: A 10th-grader was fatally shot as classes were underway at Dillard High School in Fort Lauderdale Wednesday afternoon, and another 15-year-old armed with a chrome, semiautomatic handgun was arrested shortly afterward, authorities said.

The victim, identified as Amanda Collette, was rushed to Broward General Medical Center, where she was pronounced dead, both police and school district officials confirmed. She was shot in the torso, authorities said.

The shooting suspect, a sophomore named Teah Wimberly, was being questioned -- with her grandfather by her side -- at police headquarters and has been charged with first-degree murder and one count of discharging a weapon on school property.

Broward Superintendent Jim Notter called the incident isolated, adding that the school community was ''devastated.'' He said counselors were at the school assisting students. He also mentioned that the school was equipped with metal detectors, but the detectors aren't used on a routine basis to search students as they enter the building.

''We are more than heartbroken,'' Notter said.

There was no immediate motive known, but detectives were reviewing security cameras in the school to help with the probe.
