Though a judge has sentenced one man for the murder of a Morehouse graduate, the best friend of the victim says he believes the killer did not act alone.

On Oct. 24, 2011, the body of 61-year-old Gary Bussey of Augusta was found with multiple stab wounds in a home on Homestead Road in Rex. Bussey was in town for Morehouse homecoming festivities, Channel 2 Action News reported.

A day later, authorities arrested Chinua Plez in Broward County, Fla., in connection to Bussey’s death. Plez was 19 at the time of his arrest. Bussey’s body was found in the home of Plez’s mother, whom Bussey was dating at the time.

Plez now faces life in prison without parole, but Bussey’s best friend, Eric “Tiger” Turner, told Channel 2 that after sitting in the courtroom during the trial, he believes Plez had help.

“I know the young man killed him, but he wasn’t by himself,” Turner told the news station Monday, adding that Plez looked too small to move Bussey’s body.

“Somebody helped him get out of town,” Turner added. “Somebody made sure he had money to get out of town. Somebody kept him abreast of what was going on.”

Clayton County Senior Assistant District Attorney Jeff Gore told Channel 2 that Plez’s mother gave conflicting statements about her knowledge of her son’s whereabouts when he was missing, adding that she could face charges.
