An 18-year-old Temple Hills man charged in a fatal shooting over a coat had been charged with manslaughter and car jacking four years ago and was released from the District’s Department of Youth and Rehabilitation Services last April, a source within the agency confirmed Thursday.

Donte Graves is charged with one count of second-degree murder while armed in the shooting death last month of Tyrone Joyner.

The two men got into a scuffle on Feb. 24, near Nationals Park in the 1400 block of Canal St. SW, according to charging documents. Joyner was seen by one witness chasing after Graves and grabbing a coat he was holding. The coat fell to the ground and Graves pushed Joyner away. Joyner then walked towards Graves and started to throw a punch at him. Graves, the witness said, already had a gun out, shot Joyner, grabbed the coat and ran into an alley.

It was unclear in the documents who owned the coat.

The witness said Joyner never had a weapon. No weapons were found on Joyner by paramedics or police.

Assistant U.S. Attorney Jennifer Kerkhoff argued at Graves’s preliminary hearing Thursday that he should be held in D.C. jail until his trial because he was on court supervision at the time of the shooting.

A source familiar with the case said Graves was committed to the District’s Department of Youth Rehabilitation Services after he pleaded guilty in 2008 to one count of manslaughter and assault with intent to rob. He was released from detention in April as part of a special program called “Project for Success.” The source spoke on condition of anonymity because the case involved Graves’s juvenile charges.

D.C. Magistrate Court Judge Karen Howze ordered Graves held in jail until his next hearing on March 22. Howze said she found “substantial probability” that Graves was involved in Joyner’s death.
