A 31-year-old man has been convicted for a second time of a 1998 murder at a birthday party in Atlanta, authorities said.

A Fulton County jury on Monday found Terrance Beasley guilty of felony murder, aggravated assault and possession of a firearm during the commission of a felony, according to the Fulton District Attorney’s Office.

Beasley is to be sentenced Aug. 24.

It was the second trial for the man, first found guilty of killing Rodriguez Hamm, 17, in 2000 but whose motion for a new trial was granted in 2009.

It all began with an argument at a birthday party Nov. 22, 1998, at the Brewer Street home of the victim’s grandmother.

Beasley left the party and returned with a sawed-off shotgun. He fired it, fatally wounding Hamm in the chest. Beasley turned himself in to police the next day. He was 18 years old at the time.

In an unrelated incident, Beasley was named in a lawsuit filed last year by an Atlanta studio recording technician against rapper T.I. The plaintiff, Norris Gresham, alleged that he was held hostage for 12 hours at T.I.’s studio and beaten by one of the musician’s employees in a dispute over a missing necklace.

The suit identified Beasley as one of T.I.’s associates present during the Sept. 8, 2010 incident at Echo Studios. The artist himself, whose real name is Clifford Harris, was not there, the suit says.

A spokeswoman for the Fulton District Attorney confirmed that Beasley was out on bond at the time and is the same individual named in the lawsuit.
