Cops: Unclear How Girl, 15, Died on Street

A 15-year-old girl who died on her way to mail a Christmas card bled to death internally, but the cause of her injury remains unknown, police said.
    
A preliminary autopsy report says the girl died from a lacerated liver, Bronxville Police Chief Christopher Satriale said Friday.
    
The injury was caused by blunt force trauma to the midsection, Satriale said, adding that police don't believe she was struck by a car and are investigating the possibility that she could have fallen, been pushed or been struck by a bicycle.
    
Disputing earlier reports that police believed the girl accidentally slipped and fell, Satriale said it's possible the girl slipped, but there were no icy patches at the spot, only slushy snow.
    
He said there is a high curb, a boulder and a metal railing in the area, any of which could have caused the injury.
    
Passers-by in the Westchester County village found the girl at the spot in front of a church late Wednesday morning.
    
Surveillance video shows the teenager walking down a hilly street about six minutes before 911 calls were made. Police believe the injury occurred after she was safely to the other side of the street and out of frame.
    
Police are interviewing the girl's friends, classmates and family, Satriale said.
