A D.C. Superior Court judge Wednesday ordered two District men and one Maryland man held in the D.C. jail for three separate slayings dating back to January.

Magistrate Judge Karen Howze ordered Harold M. Proctor, 19, held in in the Dec. 17 robbery and death of Kevin Blackwell Jr. Blackwell’s body was found in the 900 block of Burns Street SE with a stab wound to his chest.

According to charging documents, Blackwell, 20, called 911 for help during the robbery. His attackers can be heard saying “Come up off that North Face (jacket) cuz” and “Nah son, I’m about to stab this (expletive) son.”

Assistant U.S. attorney Charles Cobb described the 911 recordings as “chilling.”

The victim’s cell phone, jacket and beige Cadillac were found at Proctor’s home in the 10800 block of Phillips Drive in Upper Marlboro, authorities said.

In an unrelated case, the judge ordered Andrew W. Williams, 25, of Northeast Washington, held in connection with the May 14 fatal shooting of Junon T. Snead, 30, in the 3700 block of Jay St. NE. Williams is charged with premeditated murder.

An unidentified witness identified Williams as the shooter from a photo array. But Williams’ attorney, Betty Ballester, argued that the witness initially identified another person as the shooter.

Howze ordered Williams held until a Jan. 6 hearing.

Howze also ordered Anthony Speight, 23, of Southeast Washington, held in the Jan. 20 fatal shooting of William Mitchell, 33, whose body was found at the corner of North Capitol Street and Florida Ave N.W.

A witness said Mitchell was waiting at a bus stop when Speight allegedly rode up to him and demanded money. The witness said Mitchell refused to hand over cash and the assailant began shooting.

The suspect left behind a grey and white striped hat as he fled, authorities said.

According to charging documents, another witness told authorities Speight admitted to shooting a man who was “taking him for a joke.” A third witness also alerted detectives that Speight admitted that he was in the area at the time of the shooting.

Detectives searched Facebook and found a picture of Speight wearing a gray and white striped hat, which detectives say was the same type of hat that was left at the scene of Mitchell’s slaying.
