Arizona prosecutors moved to dismiss sex assault charges against the son of "Doomsday" cult mom Lori Vallow after a woman accused him of rape.

Colby Jordan Ryan, 26, was initially charged with two counts of felony sexual assault Sept. 5 for the alleged Aug. 31 attack and held on $10,000 bail. 

"This office has filed a motion to dismiss without prejudice, which allows the office to file charges in the future and allows time for additional review of the case," Maricopa County Attorney's Office spokeswoman Jennifer Liewer told Law&Crime.

The motion was granted Sept. 8 and Ryan was released from custody three days after his arrest. He ordered not to have any contact with the alleged victim, court records show.

Ryan and the woman, with whom he had been in a relationship, were allegedly watching TV when they began to have "consensual romantic contact," according to a police report.
