Maryland police hunting for man who shot, killed D.C. police officer

Police are searching for a man who allegedly shot and killed his stepfather – an off-duty Washington, D.C., police officer – at a Maryland home Monday.

Prince George’s County Police officers have obtained an arrest warrant for Antwan Rayvon James, 27, who they believe fatally shot Joseph Burrough Newell, 46, at a private residence in an Upper Marlboro, Md., gated community Monday evening.

Officials have identified Newell as an off-duty officer with the District of Columbia’s Metropolitan Police Department. A preliminary investigation suggests the slaying “stemmed from a dispute over yard work,” according to a police statement released Tuesday morning.

“We believe the shooting stems from a domestic situation,” said Officer Nicole Hubbard, a spokeswoman for county police.

Police officers responded to reports of a shooting in an upscale gated community, where Newell is believed to have lived, just after 8 p.m. Monday evening. Responding officers initially believed the shooter was hiding in the residence and erected a barricade shortly after 10 p.m.

But when police searched the home at 3 a.m., they determined that the gunman had fled and immediately dispatched officers in pursuit, Hubbard said.

“We believe the #UpperMarlboro domestic murder suspect is out of the immediate area,” authorities tweeted shortly after 3 a.m. “Active search underway.”

Newell was a 24-year veteran of the D.C. force, according to a police statement.
