22 year-old David Daffin of Hamilton was arrested over the weekend and charged with sexual intercourse without consent after an incident at a Hamilton motel.

Ravalli County Attorney Bill Fulbright said a group had stayed in the motel room, and the victim was sexually assaulted while she slept.

"The 21 year-old female victim said she awoke early Saturday morning to find this individual sexually assaulting her," Fulbright said. "When confronted, Daffin left the motel area. Later, when detectives were investigating, the defendant sent some texts to one of the witnesses that was there acknowledging the assault and that he knew it was wrong. When he was confronted and arrested by the officer he also admitted to committing the sexual assault. "

Fulbright said Daffin appeared in Ravalli County Justice Court of Monday and bail was set at $50,000. He remains in the county detention center.

According to Fulbright, David Daffin is the eldest son of Brad Daffin, who was sentenced in September to five life terms in the Montana State Prison for sexually abusing five young girls over a period of years.
