A murder suspect considered armed and dangerous is on the loose in the Lexington Park area, authorities said Tuesday.

Clarence Johnson, wanted by Annapolis Police for murder and attempted murder, was seen entering a River Bay Town townhouse in Lexington Park Tuesday, according to St. Mary’s County authorities.

Police released photographs of Johnson, who they described as an African-American standing 6 ft. 4 in., weighing 240 pounds and wearing several tattoos.

Johnson is wanted for the Dec. 12 murder of Joseph Johnson III, who is not related to him, in Annapolis, police said.
