A longtime friend invited Christopher Andrew Ramon to his home in late August to hang out and have a few drinks.
Ramon's buddy eventually passed out in the back yard. Authorities say Ramon then went inside and raped his friend's girlfriend as she slept.
Ramon, 21, was held to answer on charges of rape and burglary Wednesday. His next court hearing is scheduled for Nov. 20.
Deputies say the girlfriend went to bed about 2 a.m. She awoke sometime between 4 a.m. and 4:30 a.m. and at first believed her boyfriend was having sex with her.
She looked up, saw Ramon, and pushed him off her, according to deputies. She then told him to leave the residence and called 911.
