SANTA ANA, Calif. -- Orange County authorities have arrested an emergency room technician they believe raped an unconscious patient who was awaiting treatment.

Sheriff's spokesman Jim Amormino says Jesse Pena, 31, of Murrietta remained jailed Friday on $100,000 bail. Pena was arrested Thursday after DNA test results matched him to the crime.

Amormino says a 31-year-old woman who went to Mission Hospital in Mission Viejo in February awoke and realized she'd been raped.

Amormino says she disconnected her IV, went to a phone and called 911.

Amormino says Pena worked at other hospitals in Riverside and San Diego counties and investigators want to determine if there are other victims.

Amormino didn't know whether Pena had a lawyer.
