Four Teenagers Killed In Tank Explosion

Four teenagers are dead after an overnight explosion in Anderson County.

The Sheriffs Department says a petroleum tank in the Long Lake area exploded Friday night, while five teenagers on a camping trip played on top of the fifteen foot tall drum.

Fourteen year-old Ples Kropp, and fifteen year-old Justin Rober and Jessica Ross all died in the blast. Fourteen year-old Amanda Ross was taken to a hospital, where she died Saturday afternoon.

Although the Anderson County Sheriff's Department says they have no idea what caused the explosion, they expect to talk to another teenager who was treated and released.
