When Christian Garcia spotted two people having sex behind a dumpster outside the Gainesville, Florida, bar where he was working security early Thursday, he at first passed it off as drunken antics.

But then the University of Florida linebacker realized the woman was unconscious, according to CBS Miami.

“I mean, at that point, I’m like, this isn’t right,” Garcia told CBS affiliate WFOR-TV. “This girl is probably drunk, there’s no possible way she could’ve given consent.”

“I grabbed the guy by the shoulder and said, ‘Get off of her, this isn’t right,’ and the guy yelled at me like, ‘Mind your own business,’ ” Garcia said. “He pulled away from the girl, and then he got aggressive with me. He tried to throw a few punches; his friends were holding him back.”

Garcia told the Gainesville Sun that the man was intoxicated and that after swinging at Garcia, he slipped and “busted his face on the wall.”

Police have identified the man as Christopher Shaw, 34, according to NBC affiliate WTLV. Authorities have charged him with sexual battery and jailed him on a $500,000 bond.

The victim, according to a police reported cited by the Sun, had difficulty speaking, was unable to walk and struggled to keep her eyes open. The report says that the alleged assault, which took place behind a bar called 101 Cantina, was captured on video.

“Upon viewing the videos, it is clear the victim was mentally and physically unable to give consent due to her level of intoxication,” the report says, according to the Sun. “The victim was slumping over and unable to hold up her head. The (defendant) can be seen pushing the victim back up. . . . When pushed back up the victim’s eyes were closed, and her head fell back against the dumpster.”

Shaw told police the woman initiated the contact by pulling him behind the dumpster while he was walking through the alley, the paper reported. Beyond kissing, he denied having sexual contact with the woman – an assertion that is “completely contradicted” by video evidence, according to police.

The athlete told WFOR-TV he had some advice for young people who are out drinking.

“It’s important that you don’t leave without any friends,” he said.

“I mean, this girl, her friends had completely left her at the bar alone when she was blackout drunk.”
