Michael Alexander Brown, 22, is suspected of killing his mother’s boyfriend last week. He has been on the run ever since. On Thursday morning, a sighting of the Marine deserter tapping on someone’s house window in Roanoke, Virginia prompted officials to shut down the schools in the area. Police have now asked that anyone that lives within a half mile of Patrick Henry High School on Grandin Road to shelter in place and keep their doors locked. Anyone that must travel should stay stay extremely vigilant, officials said, as they believe Brown will be looking for a new means of transportation. Brown deserted from his command at Camp Lejeune sometime in October, but only few details have been released regarding his service thus far.

According to reports, a resident contacted police when they saw a man in a black jacket tapping on a house window early this morning. Police responded immediately and, to the best of their ability, were able to confirm that it was indeed Brown, though he managed to evade capture. Brown had previously been spotted driving a Lincoln Town Car, but police identified an RV in the vicinity of the sighting that they believe Brown had been using in recent days. The RV was secured by police at the scene.
