A Prince George’s County man faces charges of first-degree murder and first-degree burglary in a crime that is becoming increasingly common, according to security experts: criminals disguising themselves as utility workers to rob people’s homes, sometimes after an unsuspecting resident invites them inside.

Clinton resident John Haston and Craig Brooks, who dressed up as a Pepco worker, bound the feet and hands of David Williams and then shot him in the chest, fleeing with Williams’ and fiancee Scquana Majors’ belongings, Prince George’s County prosecutors said Tuesday.
