The details aren't adding up.

That's what the family of a college student from Queens killed in a hit-and-run upstate are saying about the police version of her death.

Police found 20-year old Stefani Lineva laying in a road in Binghamton around 2 a.m. Saturday.

The psychology student was in her first semester at Binghamton University and was a member of the school's tennis team.

Lineva's mother says investigators discouraged her from viewing her daughter's body because it was unrecognizable.

But she says a cremation service provider later told her otherwise.

She says her daughter attended a party the night before her death and was missing for over an hour before her body was found.

"It was a homicide, homicide, yeah," Lineva's mother said. "She was either robbed, maybe raped, thrown in a car, she might have been fighting, jumped off the car or she was thrown, or and then run over again by another car, but there's no way she would be crossing the street there by herself, no way."

A $19,000 reward is being offered for anyone with information leading to an arrest.
