HILLSBORO, Ore. -- A family returned to their home Thursday night to find a houseguest bruised, half-naked and possibly beaten.

Rebecca Roberts said she and her family returned home from Thanksgiving dinner and thought someone ransacked the house. Outside, she said she found something much worse – her friend sitting at the bottom of the stairs, half-naked and confused.

"We found her in the backyard with half her clothes off, with bruises and cuts," Roberts said.

Roberts called 911. Later at the hospital, she said her friend briefly talked about a man in a black leather jacket with fuzzy facial hair.

"She kept calling him the boogie man and was crying and kept asking not to be hurt," Roberts said.

Roberts said her friend has been in and out of consciousness and that she thinks her friend was drugged and raped.

The woman did have a date set up Thursday night with a man she met on Craigslist. Roberts said she gave the man directions over the phone and she knew they planned to go out for dinner.

That was the first time they'd ever met. Roberts said giving out her address and phone number was a mistake.

"It was every worse case scenario with dating on the Internet," she said.

Police said they found prescription drugs and drug paraphernalia in the woman's purse. They're not sure if she was sexually assaulted, but they're investigating the possibility.

Detectives are awaiting test results from the crime lab so they can find out exactly what happened to the woman.
