Kauai police suspect foul play as they investigate the mysterious death of a 21-year-old Kapa'a woman.
Officials say the unidentified woman was found dead in her room at the Kawaihau Sports Villa Condominium Friday afternoon.
The woman's 26-year-old roommate is in custody for questioning.
All police are saying about the roommate is that they may have more information to help them understand the circumstances that led to the victim's death.
County officials say they hope to have more details in the next few days as authorities work on the case.
"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," said KPD chief Darryl Perry in a statement.
An autopsy of the woman's body is scheduled for Monday.
