A Jackson man opted Thursday to face three felony charges in 9th District Court rather than go through a hearing to establish probable cause.

Robert Larry Carmichael, Jr., 27, is accused of aggravated assault, first-degree sexual assault and attempted strangulation after a fight that allegedly left his girlfriend severely injured.

Carmichael waived his right to a preliminary hearing that would have required prosecutors to convince 9th Circuit Court Judge James Radda to send his case to the trial court. The court has withheld details on the sexual assault and attempted strangulation charges, which were added two weeks after the aggravated assault charge. The file remained in Judge Timothy Day’s office all day Thursday.

Carmichael remained in jail Thurs-day afternoon. His bail is set at $100,000 cash.

Prosecutors charged Carmichael with aggravated assault following his arrest Sept. 10. Investigators believe that Carmichael and his girlfriend had an argument that day that turned violent. A family member called police after finding the woman bleeding in her bathroom. The woman was flown to Eastern Idaho Regional Medical Center where she underwent emergency surgery to repair her broken jaw and orbital bone. At a court hearing weeks later, Teton County prosecutor Steve Weichman said the woman is still speaking through a voice box, and may have to do so for the rest of her life.

Carmichael admitted to the argument, but denied physically harming the woman, according to court files. He told police he woke up in the middle of the night, and his girlfriend was bleeding and crying in the bathroom. Doc-uments in the court file also say Carmichael thought he remembered her falling and hitting her head on a rock that night, but that he wasn’t sure.

Two weeks later, Carmichael was arrested again, this time on the sexual assault and attempted strangulation charges. Weichman said at Carmichael’s initial appearance on the newer charges that Jackson police detectives conducted an investigation between the two arrests to gather new evidence.  The results of that investigation have not yet been publicly released.
