Investigators with the Nebraska State Patrol (NSP) have arrested a 40-year-old Aurora man for First Degree Sexual Assault.

On Thursday, October 20, NSP investigators responded to a victims’ report of a sexual assault. The female victim provided investigators with information about a male who identified himself as “Brandon” who she met on a social media site.

The victim indicated the two had been corresponding for a couple of weeks and that she had agreed to meet with “Brandon”. The victim was to drive to Aurora, where she would meet him at a park. He indicated he would be in a white car.

Upon her arrival at the designated location, the victim indicated she found a man waiting in a white car, but that she did not recognize him as “Brandon”. The man told her “Brandon”, was at a house in Aurora and he was to drive her there. The victim rode with him to the house. She then went inside the home with the man.

Once inside he informed her “Brandon” was not there. While in the home, the victim was sexually assaulted by the man. After the assault the man drove her back to her car.

The victim then returned to her home, where she reported the sexual assault.
