(CBS/AP) LIVONIA, Mich. - Livonia police are investigating a case that appears to be a double murder-suicide, in which authorities say a man went to his ex-girlfriend's home, axed her mother and new boyfriend to death, injured the girl, and then shot himself.
Lt. Thomas Goralski says the unidentified 17-year-old ex-girlfriend called Livonia police about 12:20 p.m. Wednesday, saying two people were dead and she was hurt. When officers arrived, they found three people dead.
CBS Detroit reports police say a preliminary investigation identifies the killer as 19-year-old Brian D. White. The lieutenant says White killed 46-year-old Angela Staperfene and 19-year-old Jacob L. Burns with axe blows to the head.
Police said it appeared the relationship between the 17-year-old and White had recently ended. Authorities say White also attacked his ex-girlfriend before committing suicide. He was found with a fatal gunshot wound to the head. She was treated at a hospital and released.
According to the Detroit Free Press, Livonia Mayor Jack Kirksey said the investigation is "still a work in progress."
Friends left a candle and flowers near the home Wednesday night.
Friend Nancy Radtke said Staperfene was a strong person. "If Angie had anything to do with it to defend herself, I'm sure she went out in a blaze of glory," Radtke said. "She was a feisty person."
Goralski says White lived in Livonia, a city of 100,000 about 15 miles west of Detroit.
