A man who worked at a Helena group home admitted to raping an elderly resident who is deaf, blind and unable to speak.
Zane Richard Frisbie, 56, is charged with sexual intercourse without consent, a felony.
Helena's interim Police Chief Steve Hagen said the incident was reported at Hillside Group Home at 10 Dayspring Loop. The home is operated by West Mont, which could not be immediately reached for comment Monday evening.
According to court documents, the group home manager reported a sexual assault on July 13. The manager told authorities the light was on and the door was closed in the victim's room, which was unusual because the door is supposed to be open when a resident is receiving care.
The manager reportedly opened the door and found Frisbie trying to rape the woman, who was unable to provide consent. Frisbie quit his job on the spot and then left, court documents state.
A Helena police officer tracked down Frisbie and arrested him. At the Lewis and Clark County Detention Center, Frisbie admitted to having sex with the victim and acknowledged she was unable to consent, according to court documents.
The Montana Department of Public Health and Human Services is investigating the incident.
