Two men suspected of robbing and killing a drug dealer in Montgomery County, Md., late last year have been charged with murder, authorities said Monday.

About 4:35 p.m. on Dec. 16, officers responded to a report of a shooting in the 12900 block of Falling Water Circle in Germantown, Montgomery County police said in a statement. They found 18-year-old Andrew Turner in his residence with a gunshot wound. He was pronounced dead at the scene, the statement said.

An investigation showed that Turner had been selling marijuana from his home, the statement said. He was robbed of marijuana and shot, police said.

Kairee Deyonte Dorsey, 21, and Christopher Arthur Breeden Jr., 23, both of Silver Spring, have been charged with first-degree murder.

Dorsey was arrested Feb. 28 during a traffic stop, according to the statement, while Breeden was arrested March 2.
