A Detroit teenager murdered his ex-girlfriend's new boyfriend and her mother before killing himself, myFOXdetroit reports.

Police say 19-year-old Brian Douglas White entered the home of his ex-girlfriend Wednesday and went on a killing rampage, murdering the girl's mother Angela Kim Staperfene and using an ax to kill the girl's current boyfriend, 19-year-old Jacob Lee Burns. He then shot himself to death.

His 17-year-old girlfriend, who has not been named by police, was injured in the attack but managed to escape and call 911.

The girl, a senior at a local high school, was hospitalized and released. Classmates and neighbors described her as a happy, outgoing and compassionate girl who was raised in a loving home.

"She's a good friend of mine," classmate Amanda Mellville told myFOXdetroit. "When I was watching the news, I was about to cry because I thought she was like in trouble. I mean, I still feel bad for her, but it's sad."
