"Date Rape" Drug Culprit as Dozen Wash. Party-Goers OD?

ROSLYN, Wash. (CBS/AP) Officers expected the revelers to flee when they arrived at a house party in a small central Washington town.

But they didn't expect the chaos they found inside after kicking down the door because no one responded, police said. Unconscious and semi-unconscious party-goers were scattered throughout the home.

"The house was packed with people. We found people passed out, incoherent, of all different levels of intoxication ... (some) in need of medical attention" Cle Elum Sgt. Monty Moore said. "There was vomit everywhere, inside and out."

One man was found engaging in a sexual act with a semiconscious female, who was later determined to be his girlfriend, police said.

In the basement, some of those who were sober had tried to help others by putting them on beds, couches or mattresses.

"However, not one person chose to call 911," Cle Elum Police Chief Scott Ferguson said.

Officers and Kittitas County sheriff's deputies went to the home in downtown Roslyn, about 80 miles southeast of Seattle, late Friday after receiving a report of a possible overdose victim at a nearby grocery store. The victims' friends told officers about the party.

As many as 50 underage people were at the party, most of them Central Washington University students between 18 and 21. Eleven women and one man ended up in the hospital after overdosing on a substance police believe may have been slipped into their drinks.

All 12 have since been released, a nursing supervisor at a hospital in Ellensburg said Sunday.

Students who attended the party believe a bottle of vodka had been spiked with the date-rape drug Rohypnol, commonly known as "roofies."

Police found no drugs at the home after a four-hour search, and investigators are still looking into what substance may have sickened the 12 and who may have been responsible.

"Some type of drug was slipped into drinks," Ferguson said. "We were talking to people who were highly intoxicated, yet admitted to having only consumed a couple of beverages."

Ferguson said his department is planning to meet Monday with other police agencies to coordinate interviews with everyone in the house. They're also waiting for toxicology tests from the state crime lab on blood and urine samples taken from the victims.
