ASHVILLE - Alabama authorities say a 14-year-old boy is charged with murder for the death of a girl found hanging from a tree.

Her body was discovered Thursday night outside her home in Ragland, a rural town about 40 miles northeast of Birmingham.

Neighbors told reporters the rope used to be part of a tire swing

St. Clair County Coroner Dennis Russell said an autopsy found the cause of death was homicide due to ligature strangulation.
