The man accused of killing an Atlanta attorney in a Midtown crosswalk waived his first court appearance Thursday, the Fulton County Sheriff’s Office said.

Raylon Lee Browning, 39, was being held in the jail's medical unit for undisclosed reason, according to the sheriff's office spokeswoman. Browning is accused of shooting and killing Trinh Huynh as she walked on Peachtree Street around 7:40 a.m. Monday.

Monday evening, Browning allegedly ran a red light and was stopped by a Cobb County officer, according to police. That officer determined Browning was a wanted man — he was the suspect in a double stabbing Sunday. Browning was held overnight in the Cobb jail and Tuesday morning, detectives identified him as the suspect in Huynh’s death.

After being moved to the Fulton jail Tuesday, Browning's violent acts continued, according to the sheriff's office. Tuesday night, he allegedly punched another inmate four times in the face and was found chewing on his own arm, incident reports showed. Deputies were forced to deploy their Tasers to stun Browning, who was taken to Grady Memorial Hospital for observation. He was returned to the jail Wednesday night.

Browning’s next court appearance is scheduled for April 20 at 9:30 a.m. on the murder and aggravated assault charges related to Huynh’s death. On April 21, he must appear in court on a simple battery charge which was added after the fight in jail.

The Georgia Asian Pacific American Bar Association will hold a candlelight vigil Thursday night to honor Huynh. The vigil is planned for 7:30 p.m. at 999 Peachtree Street.
