Marine Philip Bushong, 23, is dead after an altercation over a gay slur.

Police in the District of Columbia have taken into custody Michael Joseph Poth, 20, also a Marine.

Bushong, who was based at Camp Lejeune, North Carolina, was stabbed once in the chest with a pocketknife during the altercation which happened Saturday between 2:30 – 2:45AM in the 700 block of Eighth Street SE, just blocks from the Eastern Market Metro. Bushong was taken to a hospital where he was pronounced dead.

The Marines got into a fight when the suspect called the victim an anti-gay slur. However, there was no reason to believe either man was gay.

“One witness heard a homophobic slur during a verbal altercation that preceded the stabbing,” homicide Lt. Robert Alder told The Washington Post.

Poth, who lives in the nearby Marine barracks, was charged with second-degree murder.

Bushong had earlier stopped in at the Ugly Mug bar and restaurant.

“He was a very lighthearted, good young man,” Ugly Mug general manager Brent McCaslin said. “He was one of our frequent customers. It's a sad loss.”
