A Riverdale teenager accused of shooting to death a Clayton County sheriff's deputy in July, wants the district attorney's office disqualified from prosecuting him.
Johnathan Bun, 17, is due Tuesday afternoon in Clayton County Superior Court on several motions filed on his behalf. Bun also wants the case moved to another jurisdiction, because of pretrial publicity, and is again seeking bond.
He has been held without bond in the Henry County Jail since his July 20 arrest. He has been indicted, and faces murder charges in the shooting death of Deputy Rick Daly.
District Attorney Tracy Graham Lawson has already recused herself from the case. Lawson previously served as a Clayton County Juvenile Court judge and was involved in some of the juvenile proceedings involving Bun. She is expected to testify in Tuesday's hearing.
Daly was assisting in a traffic stop to arrest Bun on felonies related to a January armed robbery and aggravated assault at a Forest Park store. Testimony from witnesses revealed that Bun, allegedly opened fire on Daly even before the car Bun was riding in came to a complete stop.
Since his arrest, Bun has made a flurry of court appearances on that case and a handful of others from the months preceding Daly's shooting death.
In August, Bun pleaded no contest to misdemeanor charges related to an incident on his May 15 birthday. He was cited that day for possession of less than an ounce of marijuana, and criminal trespass.
After entering his plea, Bun was sentenced to 24 months in jail. He is serving his sentence in the Henry County Jail, where he is being held without bond on felony charges from separate cases, including Daly's shooting.
He is a suspect in the armed robbery of Illusions Hair Studio, in Riverdale, but has not been charged. Police said Bun and Xavier Carter, 18, of College Park, entered the business and took cash from patrons. Brandishing a gun, Bun allegedly demanded money from customers while Carter locked the door and closed curtains to hide the incident, according to a warrant in the case.
Carter was arrested in that case in August, and is being held on $100,000 bond in the Clayton County Jail.
Bun has an extensive juvenile criminal history in Clayton County, dating back to age 10, which led to Lawson's recusal.
If convicted of murder, Bun could spend the rest of his life in prison.
