(Updated at 3:15 p.m.) Arlington County Sheriff’s Deputy Craig Patterson has been charged with murder in the shooting death of 22-year-old Alexandria resident Julian Dawkins.

“Earlier today, the Commonwealth’s Attorney requested that detectives apply for an arrest warrant for Patterson,” Alexandria police said in a press release. “The warrant was issued this afternoon and Patterson was taken into custody at a residence in Spotsylvania County this evening. No further details about the arrest are being released at this time.”

Patterson, 44, was placed on paid administrative leave from the Arlington Sheriff’s Office following the May 22 shooting, which took place in Alexandria near Potomac Yard. According to scanner traffic that night, Patterson, who was off-duty, said he shot a man who pulled a knife on him.

Dawkins was a shuttle driver for the PBS NewsHour, which is produced in Shirlington.

Patterson was denied bond during his arraignment Friday morning, according to Del Ray Patch. At a press conference, prosecutors said that Patterson was seen arguing with Dawkins, walking away, then returning with his badge, gun and handcuffs. Dawkins had a pocket knife, but it was folded up and in his back pocket, WUSA reported.

As of Friday, the Arlington Sheriff’s Office has placed Patterson on unpaid administrative leave “pending the outcome of an internal investigation,” according to a news release.
