Anton Jamail Harris, the 18-year-old suspect arrested for the Medical Center rape cases, has been charged in an additional case of aggravated sexual assault.

According to the affidavit released Monday morning, the victim returned to her apartment from grocery shopping. The victim said she was putting her groceries away when she heard the front door of her apartment open and saw a man walk in holding a knife. He then instructed her to lie on the floor face down and to take off her pants.

The woman said the man sexually assaulted her before demanding money. The victim said she had no money, so the man left.

DNA evidence collected at the scene was compared to all other related cases and was found to be a match.
