Police arrested a District man Wednesday in the killing of a dog in Northeast Washington late last month, according to the Washington Humane Society, which investigates animal cruelty cases.

Police arrested Sean D. Branch, 24, of Northeast Washington in connection with the case, in which a heavy concrete slab was dropped on the head of a dog which was sleeping behind a convenience store at 1209 Mount Olivet Rd. NE.

Branch is charged with one count of felony animal cruelty. He faces up to five years in jail and a $25,000 fine, the humane society said in a release. He is scheduled for a preliminary hearing July 31. Branch was arrested in Clinton, the humane society said.

Officer Michael Triebwasser of the Washington Humane Society said that the 6-month-old dog, King Tut, a brindle-and-white male, fell asleep about 9 a.m. in the shade behind the Circle Seven Express store on Mount Olivet Road. According to court documents, the dog’s owner is Willie Starkey of no fixed address.

The assailant, described by witnesses as a man in his late 20s, picked up a large concrete slab, held it chest-high and then let it fall on the dog’s head, Triebwasser said.
