A grand jury convened in Boulder, Colorado, handed down an indictment against a local man that accused him of giving a female acquaintance an injection of insulin and sexually assaulting her while she was dazed. The defendant was arrested by police the morning of Jan. 17 and taken to jail, where he is being held on $100,000 bond.

Authorities said the sexual assault occurred in February 2011. The suspect met a woman at a bar in the Pearl Street Mall and the two went to her home.

Likely due to the secretive nature of grand jury hearings, details of the Boulder County prosecutors' account of what happened next were scarce in a news report by KCNC-TV. The defendant told authorities that he and the woman had consensual sex. The next afternoon, the woman's roommate heard a wheezing sound coming from her room, which had a locked door. Nine hours passed and the roommate forced her way into the room. The victim was catatonic and bruised with no clothes on, prosecutors said.

Doctors told the grand jury that the woman was suffering from severe hypoglycemia. They said the likely cause of the hypoglycemia was an insulin shot, which can cause loss of consciousness. Police claim that the defendant told them that he is a diabetic who generally carries an insulin kit when he goes out. It is not clear if the victim was diagnosed with receiving an insulin injection.

The grand jury indictment included nine counts, including five counts of sexual assault.
