Antwan Rayvon James, Md. man accused of killing his detective stepfather, turns himself in

(CBS/AP) MARLBORO, Md. - A 27-year-old man accused of killing his stepfather turned himself in on Tuesday night after a day-long manhunt, reports CBS DC.

Antwan Rayvon James, a former Washington, D.C.  firefighter, allegedly murdered his stepfather at his home in a gated community on Monday in what is being described as a domestic dispute. 

Officials said a neighbor's surveillance system captured the incident on video. CBS DC reports that authorities say the video shows Newell on a ladder changing a light bulb when James shot him with a handgun. After the 24-year veteran detective fell, James allegedly stood over his stepfather and fired multiple shots directly into his body.

"It was an execution," Prince George's County Assistant Police Chief Kevin Davis said at a news conference.

Newell was reportedly the father of two teenage daughters and three stepchildren, all of whom resided in the home. He had been a detective with the Metropolitan Police Department, reports CBS DC.

Court records reportedly show that James recently violated his probation on a second-degree assault case, and had also been given probation for a past drunk-driving case. According to CBS DC, police said he was fired from his job as a firefighter sometime in the last 18 months.
