A 21-year-old Kauai woman was found dead at home Friday and police suspect foul play.

The woman was found in her room at the Kawaihau Sports Villa condominium in Kapaa at around 2:30 p.m. Friday, Police Chief Darryl Perry said in a news release.

Police have not yet released her identity.

Detectives have reason to suspect foul play, Perry said.

Police launched a search for the woman’s 26-year-old roommate, wanted for questioning in connection with her death. He was found at around 1:30 p.m. Sunday and remains in custody.

 “This is an ongoing investigation and details of the case will be released when appropriate,” said Assistant Chief Roy Asher of the Investigative Services Bureau. “But at this time we do have a person of interest in custody that may have more information to help us understand the circumstances that led to the victim’s death.”

An autopsy is scheduled for Monday.

Perry added, “Our deepest condolences go out to the family of the victim. Please be assured that while every investigation of this kind is unique to its own set of circumstances, KPD will work in conjunction with the Office of the Prosecuting Attorney to use every resource available to identify and apprehend any offender.”
