Mass Overdose Stuns Central Wash. U Dozen students hospitalized after drinks spiked By Rob Quinn, Newser Staff Posted Oct 11, 2010 5:52 AM CDT 42 comments Comments Police say the partygoers that were still conscious fled and hid when they arrived at the house in Roslyn, Washington. (YouTube) (Newser) – Police believe a mass spiking of drinks was responsible for turning a house party in rural Washington state into a nightmare. A dozen Central Washington University students, mostly young women, were rushed to hospital after they overdosed; some say that the date-rape drug Rohypnol had been mixed into their beverages, the Seattle Post-Intelligencer reports. Police say they arrived at the party to find people lying unconscious inside and outside of the house. "Everything was going fine, the music was playing, people were having fun—and then all of a sudden all the girls were puking everywhere," says a student who was at the party. "Girls were outside on their backs." The partygoers that were still conscious attempted to flee as police arrived, with some even hiding under insulation in the attic. No arrests have been made and investigators are still trying to confirm the identify of the drug that was used, as well as determine if the spiking was part of a sex assault scheme.
