Violent Jailhouse Fight Leads to Charges Against Six Inmates in Cobb County, Disfigurement of Victim

COBB COUNTY, Ga. — Six inmates are facing new criminal charges after authorities say a violent fight broke out inside the Cobb County Adult Detention Center, leaving another inmate seriously injured.

According to arrest warrants, the incident occurred around 11:30 a.m. on Dec. 5 inside a housing dormitory at the jail. The altercation was captured on facility surveillance cameras and later reviewed by investigators who charged Quintavious Demarious Sims, 25, of Griffin; Alonzo Ross, 25, of College Park; Joshua Robinson, 23, of Mableton; Reshard Marquis Lee, 21, of Marietta; Shawn Vernard Garrett, 27, of Douglasville; and Braelyn Brown, 32, of Union City.

All six men are charged with felony rioting in a penal institution and misdemeanor simple battery. Authorities allege the group repeatedly struck another inmate with closed fists, targeting the victim’s face and torso.

Robinson faces an additional and more serious charge of felony aggravated battery. Investigators allege Robinson placed the victim in a chokehold, punched him, and kicked him in the face, resulting in what warrants describe as “serious disfigurement.” The victim reportedly suffered a laceration to the back of the head, red markings around the neck, facial abrasions, a swollen eye and nose, and a brain hemorrhage, according to court documents.

Prior Jail Violence

Records show that Robinson and Lee were previously charged in connection with a separate jail fight in June, raising additional concerns about repeated violence within the detention center.

All six inmates remain in custody. Several are being held on additional law enforcement holds from other agencies:

– Robinson has a hold from Douglasville Police and the Douglas County Sheriff’s Office
– Ross has a hold from Atlanta Police
– Brown has a hold from Union City Police
– Sims has a 108 hold

While jail fights are not uncommon, the severity of the injuries in this case has renewed attention on inmate supervision, classification, and safety within the Cobb County jail system. The use of surveillance footage played a key role in identifying those involved and filing charges. The case will proceed through Cobb County Superior Court, where the six men could face additional prison time if convicted.

County officials have not released further details about the victim’s condition or whether the incident has prompted any internal policy review.

Incidents of serious inmate-on-inmate violence frequently lead to civil litigation, and this case could expose Cobb County to legal action/ Under federal and state law, jail officials have a duty to take reasonable steps to protect inmates from known or foreseeable harm. If the injured inmate suffered lasting or permanent harm—as suggested by reports of a brain hemorrhage—damages sought in any lawsuit could be substantial and potentially include medical costs, pain and suffering, and punitive damages.

County officials have not commented on whether the fight has triggered an internal investigation or whether any staff actions are under review.
