LANCASTER, Pa. (CBS/AP) — A 14-year-old girl has been charged in the stabbing death of her older sister in a Lancaster County home, authorities said. Prosecutors said the girl called 911 shortly after 1 a.m. Monday and then pointed arriving officers to a bedroom of the Manheim Township home, where her 19-year-old sister was found with a stab wound to her neck.

First responders provided live-saving efforts, but the victim was pronounced dead at the scene, prosecutors said. Prosecutors said the parents of the sisters were asleep at the time.

The district attorney’s office said the teen will be charged with criminal homicide as an adult because homicide is not considered a delinquent act in the commonwealth of Pennsylvania. Prosecutors said a motive is still being sought as well as the circumstances of the death.

Chief Thomas Rudzinski of the township police department called it “just an awful situation.”

“I can’t imagine what those parents are going through today,” he told WHP-TV. “I’m sure they are upset to say the least over the loss of one and the second one is in prison as well.”
