Riley Mullins is accused to hitting a woman in the back of the head and then taking off with her purse and iPod. She didn't get a good look at her attacker, but did see that he had a neck tattoo of a triangle.
The next day, she received a friend request from Mullins and recognized him as the man who allegedly robbed her.
According to the Kitsap Sun, "When she saw the picture [of the suspect] she immediately recognized him as the person who assaulted her and robbed her."
Police were able to confirm that the account belonged to Mullins and he was arrested.
