Girls on murder counts

Two teenage girls face murder charges in the stabbing deaths of one of the girl's grandparents after police captured the pair at a beach house on the Georgia coast.

Holly Ann Harvey, 15, and Sandra Ketchum, 16, allegedly used a kitchen knife to kill Harvey's grandparents, Carl and Sarah Collier, both 77.

"Our investigation indicated they were doing this for freedom and so they could be together," said Fayette County Sheriff Randall Johnson.
