There's still no suspect and apparently no solid leads, but one mystery about an EMU senior's death Dec. 11 is answered, Mara Macdonald of WDIV reports. 

Julia Niswender was found dead in her bathtub in an unnatural position, say police and the 23-year-old Eastern Michigan University student's family members.

Niswender's bedroom at her Ypsilanti apartment was messed up, with items missing, police say. . . .

The cause of death was asphyxiation by drowning, and police do not believe it was an accident.

Macdonald spoke to the victim's mother, Kim Turnquist, who says:

"Now knowing what had taken place doesn’t make it any easier but I’d rather know than not know."

A family friend offers a $10,000 reward for information leading to an arrest and charges, according to WDIV.

AnnArbor.com quotes Ypsilanti Police Chief Amy Walker as saying investigators interviewed more than 100 people for possible leads.
