DETROIT (AP) - Police say the shooting of four teenagers in Detroit may have been a robbery "gone bad."

A 16-year-old girl from Grosse Pointe Woods was killed and three others were injured Monday night on Detroit's east side. A parked car full of suburban teens was repeatedly shot by a man in an out-of-the-way neighborhood.

Detroit police spokesman Adam Madera says detectives are "working under the impression it was a robbery gone bad." He says investigators Wednesday have a better understanding of what happened after interviewing the victims.

One teen remains in the hospital. Paige Stalker was killed. She was a top student at University Liggett School, a private high school in Grosse Pointe Woods.

Dozens of friends attended a candlelight vigil under holiday lights at city hall Tuesday night. Classmate Alexander Minanov says it's "just really sad" that Paige's family has to prepare for a funeral instead of Christmas.
