D.C. middle school principal Brian Betts was the third gay man in the Washington area who was targeted for a robbery and killed in recent months.

A third 18-year-old accused of shooting Betts to death in his Silver Spring home was charged Tuesday with murder, armed robbery and conspiracy. Deontra Gray’s two accused accomplices, Alante Saunders and Sharif “Reef” Lancaster, were charged Monday with murder, armed robbery and use of a handgun in a violent crime. All three were held without bail Tuesday.
