Georgia ? Authorities in Georgia say a 14-year-old boy awoke from a bad dream and shot his stepsister in the head 10 times while she napped on the couch.

Richmond County Sheriff’s Lt. Scott Peebles says Eric Lee Phillips Whitehead has been charged with murder. Whitehead is charged as an adult in the Friday afternoon death of 22-year-old Patricia Ann Troglen.

The teen told authorities he considered his stepsister to be his best friend, but he became enraged after he dreamt about an argument with her.

Police say the teen awoke, got a gun from his stepfather’s room and shot his stepsister.

Peebles says Whitehead had been in and out of trouble and had been staying at his stepfather’s home temporarily.
