WILLIAMSTOWN, Pa. -- A Dauphin County teen is in prison after police say he killed his brother over a dispute about a girl.

Dakota Thornton, 15, is in jail for allegedly shooting his 18-year-old brother, Dominick with a shotgun over his brother's girlfriend.

"The brothers were having a dispute over a young lady." Said Dauphin County District Attorney Ed Marsico. "Both of them apparently were romantically interested in this young girl and that's what lead ultimately to the killing"

Nicole Davis says she's surprised, "because I know all of them I just wouldn't imagine Dakota doing something like that."

Davis lives a few doors down from where state police say the shooting happened.

It was in apartment 3, around 2:00AM Wednesday morning when police confronted Dakota and he put his hands up and said, "I shot my brother," according to court documents. The coroner arrived and pronounced Dominick Thornton dead at the scene.

Marsico says, "It's certainly unusual to have a case where a brother shoots and kills his brother especially the ages of these individuals."

All Dauphin County homicides are handled in the adult court system. Dakota faces charges of first degree murder and possession of a weapon.
