The shooting happened around 3 p.m. Sgt. Jake Smith with Gwinnett County Police said the officer was shot while responding to reports of a suspicious vehicle parked at Crumps Landing and White Road near Shiloh Middle School in Snellville. A person anonymously called 911 to report people potentially smoking pot, according to police.

As Toney and the other officer approached, they were shot at from inside the suspect vehicle. One of those shots hit Toney, according to Gwinnett Police. Toney was shot at before he even was able to walk up to the car to talk to the people inside, Smith said. The other responding officers pulled him to cover. Gwinnett Police confirmed the other officer returned fire but it is unclear if the suspect was hit.

Witnesses told police there were four people in the car, which fled the scene.

The suspect later died at the hospital.

About two hours later, on Interstate 75 in Bartow County, a Georgia State trooper pulled over a woman for driving too slowly in the left lane. He called for backup after spotting meth and gun in the car. He put the woman and a man riding with her in handcuffs. But it turns out the man was wanted for a parole violation.

The man allegedly had a gun hidden on his back and turned around to shoot the trooper whose bullet-proof vest ultimately saved him. But the shooter was ultimately killed when two officers returned fire.

Police also responded to an officer-involved shooting in Richmond.

The Terrell County shooting that happened just before midnight brought the total cases of shootings involving police or deputies in Georgia during 2018 up to 75. The total number of police-involved shootings in Georgia for all of 2017 was 97.
