A District man was sentenced to 13 years in prison for a shooting that left another man death in Northeast Washington in July 2008, U.S. Attorney Ronald Machen Jr. announced Thursday.

John Youngbey, 30, pleaded guilty in September to second-degree murder for fatally shooting Robert Mallory, 19, with an assault rifle.

Youngbey said that on July 16, 2008, he was part of a group who drove in a minivan to the area of the Pentacle Apartments in Northeast. One of his companions, a woman, got out of the car and went into one of the residences.

While the group waited for her to return, another group of young men including Mallory approached the minivan.

An argument ensued, according to authorities, and a member of Mallory’s group fired a gun at the minivan. The shot missed, and Youngbey’s group drove away.

Later that evening, Youngbey and the others returned to the Pentacle Apartments to pick up the woman they left behind earlier. This time, Youngbey had an assault rifle with him, police said.

As the group drove past the 1500 block of F Street NE, Youngbey spotted Mallory. He got out of the minivan and chased Mallory. When Youngbey caught up with him, he shot Mallory several times before returning to the minivan with the weapon and driving away, police said.

Mallory died from his injuries.

Youngbey was sentenced to 13 years in prison, followed by five years of supervised release.
