A second suspect has been arrested in the stabbing and strangulation death of a 56-year-old D.C. man on the last day of 2011, police announced Wednesday.

Mark Anthony Coats, 28, of the District, was arrested Tuesday and charged with first-degree murder while armed in connection with the slaying of Leroy Studevant.

Police said that Studevant’s body was found around 7:30 a.m. on Dec. 31, 2011, near a creek in the 4200 block of Hunt Place in Northeast, not far from the Anacostia Freeway.

Studevant, who was unconscious when police found him, was later pronounced dead. The chief medical examiner’s office ruled that the cause of death was strangulation associated with piercing blunt force trauma, authorities said.

Coats is the second suspect arrested in connection with Studevant’s death. Alex Jerome Cater, 31, of the District, was arrested in May, 2012 and charged with second-degree murder while armed.
