Summerville Police were called about a disturbance on West Washington Street on Sunday afternoon.  When police arrived on the scene, they found Brittany Sturgeon standing in the roadway.  Sturgeon told the responding officer that her boyfriend, Matthew Mullican, had struck her numerous times. When officers spoke with Mullican, he said that he and Sturgeon had been drinking and started arguing about another woman.  Sturgeon then reportedly locked Mullican out of the bedroom and he then knocked the door in.  At that point, Sturgeon allegedly struck Mullican and he struck her back.  Police determined that both parties were at fault and arrested both, charging them with disorderly conduct.
