James Morsbach was arrested in May on stalking and window peeping charges.

On Thursday, Fort Collins Police announced new evidence linking Morsbach to an unsolved sexual assault. He now faces additional class 3 felonies for sexual assault and second-degree burglary.

Morsbach remains in custody at Larimer County Jail.

The incident occurred around 4 a.m. on May 5 when a woman told authorities she woke up to find an unknown male sexually assaulting her. Evidence was collected on the scene of Sherwood Street incident but a suspect wasn't initially identified.

After Morsbach was arrested on the stalking and window peeping charges, authorities found additional evidence linking him to unsolved sexual assault.

Detectives said they are concerned that additional people may have been victimized by Morsbach. Anyone who may have been victimized by Morsbach is encouraged to contact Detective Brandon Barnes at 970-416-2051.

“Sexual assault is a widely under-reported crime,” said Fort Collins Police corporal Tessa Jakobsson in a press release. “Our officers, detectives, and victim advocates are sensitive to the impact of this trauma and strongly encourage victims to come forward so we can connect them with recovery resources and hold perpetrators accountable.”

All suspects are innocent until proven guilty in the court of law. An arrest is merely an accusation of a crime by law enforcement.
