Man accused of copying hotel room key before assault

According to the prosecutor’s office, the suspect was in Auburn Hills, Michigan on Aug. 14. The victim was a guest at a local hotel where the incident occurred.

“It is alleged that the defendant had a copy made of the victim’s hotel room key, gained access to her room, and sexually assaulted her before abruptly flying back to Arizona,” the prosecutor wrote in the news release. “The victim reported the attack to law enforcement and charges were issued.”

The prosecutor's office did not answer questions about how the hotel room key was copied but Oakland County Prosecutor Karen McDonald said in the release that the sexual assault has had an “immense” impact on the community.

She said the office’s Special Victims Unit handled the case.
