WARNING: GRAPHIC

Murder suspect Lori Vallow's only surviving son, Colby Ryan, has been charged with sexual assault in Arizona after a female victim accused the 26-year-old of raping her. He is being held on $10,000 bail.

Arizona officials filed two counts of sexual assault against Ryan for allegedly forcing his wife to have sex after she repeatedly said no, court documents show.

He was released on bail Tuesday following his initial court appearance in Maricopa County. 

His wife initially reported the assault two days after it occurred. The married couple had been "separated" and were living in separate areas for about a month when the alleged assault happened, according to a police report.

Ryan and his wife were watching TV when they began to have "consensual romantic contact" until Ryan's wife decided she did not want to go any further. She reportedly said, "Stop," "This isn't a good idea," and "I don't want to do this," but Ryan allegedly continued, according to police.

Ryan's wife then locked herself in her bedroom while Ryan slept on the couch for the remainder of the evening. The next morning, Ryan's wife apparently recorded a conversation between herself and Ryan in which her husband "agreed that he ‘raped’ the victim, admitting that he continued with sexual intercourse until ejaculation even after she told him to stop," the police report states.

Ryan made headlines recently after appearing in a Netflix trailer for an upcoming documentary series about his mother, who is accused of killing her two younger children in 2019 collecting social security benefits in their names after their deaths.

"Are you sorry for me, or are you sorry for my siblings?" Ryan can be heard saying to his mother on a phone call in a trailer for the upcoming series titled "Sins of Our Mother." "I would've never thought you would've done something like this."

The pair is at the center of a tangled case that involves a bizarre apocalyptic religious belief that prosecutors claim the couple designed to justify the murders.
