SAN ANTONIO — Shawn Wayne Collier, 22, is being charged with sexual assault after the victim reported it to officials.
The victim, who is under 18, told police it happened in the early hours of the morning March 13.
An affidavit says to the party was at a cousins apartment in the 5000 block of N Loop 1604 East.
While there, the victim told officials she had too much to drink, causing her to get sick in the bathroom.
According to court documents, after she got sick, Collier helped her to a beige couch in the front room, where she soon fell asleep.
The victim told police at 4 a.m., she was woken up to Collier sexually assaulting her, but was too weak to force him off and he would not listen to her when she told him to get off.
After Collier assaulted her, the victim told officials she went to the bathroom and locked herself in, where she called a friend for a ride home.
Officials said the victim could identify Collier easily, as they had known each other for five years.
Collier is currently free on a $50,000 bond.
