Authorities said a Hall County sheriff's deputy was killed Sunday night in a shootout with several suspects linked to car thefts and robberies on weekends.

The deputy, who is not being appointed until his family is notified, was transferred to Northeast Georgia Medical Center, where he died.

He was one of the many officers who tried to stop a stolen vehicle he was looking for in connection with the crimes committed over the weekend, said Hall County sheriff's deputy Derrick Booth. They took several guns in the robberies, which he said gave the officers a sense of urgency. The vehicle was wrecked and several people jumped and started running, which caused a chase on foot.

Officers exchanged gunfire with suspects in the Jesse Jewell Parkway and Highland Avenue area in Gainesville shortly after 11 pm, according to the sheriff's office. The murdered deputy and a suspect were injured.

"One of the suspects, believed to be the shooter, was hit by gunfire and was also taken to the medical center for treatment," Booth said in a press release. "His condition is unknown at this time."

There is active persecution on Monday for the remaining suspects, which the authorities consider to be armed and dangerous. Gainesville police, Gwinnett County police, and Georgia State Patrol patrollers join the search.

A description of the suspects is not available on Monday morning, Booth said. The sheriff's investigators are working to interview people of interest and other parties.

"It's a kind of mixture of sadness, tragedy, horror, with a lot of work ahead," Booth told Channel 2 Action News from the scene.

One person was put in handcuffs around 7:30 a.m., but the authorities did not identify him or say what connection, if any, has to do with the deadly shooting.

The GBI has been called in to investigate, what Booth said is the standard procedure of the sheriff's office in the event of a shooting involving an officer. The agents are on the scene and have blocked a block off Highland Avenue, a narrow residential street in downtown Gainesville.

The fatal incident is the 42nd officer involved in the shooting that the GBI has investigated in 2019, a spokeswoman for the agency said. The Atlanta Journal-Constitution also tracks the shootings involved by officers who do not involve the GBI, and those numbers sometimes differ from the GBI account.

According to the records, the Hall County sheriff's killer is the fourth officer killed in the performance of his duty in Georgia.

Glascock County Sheriff's Deputy Joshua Ryer Jr., of Gibson, died January 29 in a two-car accident while on his way to pick up an inmate, the Georgia State Patrol said. He had just graduated from the police training program at the Augusta Technical College some six months before his death, according to the records of the Georgia Peace Officers' Training and Standards Board.

The deputy sheriff of Forsyth County, Spencer Englett, 29, died on April 4 after suffering a "traumatic medical event" during a training exercise, authorities said. It was his first day of training at the Georgia Public Safety Training Center in Pickens County, said Sheriff Ron Freeman at the time. It is not clear what was the "traumatic medical event" that led to his death.

And the Savannah police sergeant. Kelvin Ansari, 50, was shot dead on May 11 when he and another officer were ambushed by a robbery suspect. He was an army veterinarian and father of four children.

At this point in 2018, two Georgian officers had died in the line of duty. The final account at the end of last year was six.
