A 50-year-old Helena man is accused of threatening to kill his partner, possession of methamphetamine and sexual assault.
Robert Randall Granholm is also being charged with criminal possession of drug paraphernalia.
An officer was called to an altercation in the afternoon of Jan. 23. The victim said that Granholm had assaulted her earlier in the day, slapping her and pushing her into the wall and then threatening to kill her if she called the police, according to court documents.
The night before, the victim said that Granholm had sexually assaulted her, according to court documents.
When officers spoke with Granholm, they found a crystal-like substance in a plastic baggy that tested presumptive positive for meth, as well as a glass pipe with a burnt substance on it, according to court documents.
