A woman found strangled in her apartment Sunday in northwest suburban Schaumburg may have been sexually assaulted, according to police.

Officers went to the apartment Sunday in the 2600 block of Clipper Drive to check on 33-year-old Tiffany Thrasher, and found her body inside, according to Schaumburg police.

An autopsy Monday found she died of strangulation, and her death was ruled a homicide, according the Cook County medical examiner’s office.

Police believe Thrasher was strangled between 8 p.m. Saturday and 8 a.m. Sunday. Detectives were interviewing friends, family members and associates to develop leads, but no one was in custody as of Tuesday afternoon.

Detectives believe the suspect entered Thrasher’s apartment through a ground floor window which was unlocked, police said. They also believe she may have been sexually assaulted, but are waiting for results from the crime lab to confirm.

“The Detective Division is coordinating with the Major Case Assistance Team (MCAT) to further ensure all resources are being utilized in this investigation,” a statement from police said.

Police also issued a community alert to residents of the northwest suburb Tuesday afternoon, and said the number of patrol officers and detectives in the area has been increased.

Anyone with information should call detectives at (847) 882-3534 or 911. Anonymous tips can be called in to (847) 348-7055.
