5 Infamous Cold Cases of Murder

Five members of the Gangster Disciples street gang were found guilty Monday of torturing, sodomizing and murdering a police informant in 2016, then leaving his body in the trunk of a car at an Atlanta metro station.

Christopher Lockett, 30, Xavier Gibson, 23, Quatez Clark, 21, Joshua Rooks, 27, and Jasper Green, 27, were convicted of murder, participating in criminal street gang activity and other felony charges, the Fulton County District Attorney’s Office said in a statement.

The five men, all members of the Gangster Disciples, killed Christopher Dean, 33, at a house in Atlanta in October 2016 after finding out that he was once a police informant in California, according to authorities.

Lockett invited Dean to Xavier and Orlando Gibson’s Atlanta home, the DA’s office said. Dean was going to the house to complete a drug transaction, but before he arrived, Lockett found out about Dean’s police past, and the men devised a plan to torture Dean.

When Dean arrived, he encountered Lockett, the Gibson brothers, Quatez Clark and Joshua Rooks.

“For over an hour, Dean was brutally beaten with a two-by-four and a crow bar. The defendants also sodomized the victim with a handle-like object, and seminal fluid was found inside Dean’s rectal cavity,” the DA’s office said. “Following the savage beating and torture, the defendants shot the victim twice in the back of the head.

Rooks then picked up Green and Lamar Almon, and the three returned to the scene of the murder where Lockett paid Almon and Green to “clean up brain matter and blood from the scene of the murder and to burn the victim’s body and his car,” the DA’s office wrote.

Originally, the perpetrators were going to burn Lockett’s car with Dean’s body inside, but Green and Almon decided to leave the car and Dean’s body in the trunk.

Dean’s body was eventually discovered at the H.E. Holmes MARTA station, and all seven defendants were eventually arrested in connection to the crime.

Following the guilty verdict, Fulton County District Attorney Paul L. Howard said that the crime represented the “most horrific death” in the county’s history.

“My greatest fear is that we would choose to do nothing and the violence would happen again and again….” he said in a statement.

The Gangster Disciples were started in Chicago in the 1970s after two other gangs, the Black Disciples and Supreme Gangsters, combined forces, according to The Daily Beast. They’re now active in at least 24 states across the country, including Georgia.
