SEATTLE, WA (KTRK) --Four teenage boys are facing charges after police say they gang raped two girls during a high school field trip.
Police say the assaults happened during a three-day stay in Seattle for a school conference last October.
The district maintains when they learned of the rape allegations at Mount Rainier High School in Des Moines, it took appropriate action.
District guidelines state that male and female students are never supposed to be in the same hotel room during trips like this.
Court documents reveal the accused students invited two 15-year-old girls to their room for a party complete with alcohol and marijuana.
After allegedly taking two shots each, the girls began to feel under the influence and were told to lie down on the beds. That is when prosecutors say the boys took turns raping them.
The girls didn't report the gang rape until they returned home.
The district says it takes these allegations seriously, and that student safety is a top priority.
School officials say students were supervised by chaperones, who were supposed to check to make sure each student was in their assigned rooms.
Donnie Ray Moore and Keegan Piper are both being charges as adults. They both allegedly admitted to having sex with the girls, but claimed it was consensual.
One girl told police she said "no" to the boys several times, but they wouldn't stop the assault. The other girl said she felt like she had to do what they wanted.
All four boys will be arraigned on February 24.
The family of one of the accused declined to comment.
