A Hall County Sheriff’s Office sergeant was hit in the head by an “unknown object” from a vehicle in a wreck and injured after midnight Saturday, June 30, on Browns Bridge Road in Gainesville.

Georgia State Patrol said Sgt. Matt Venable was taken to Northeast Georgia Medical Center with injuries that were not life-threatening. The injuries were considered “serious,” Sheriff’s Office 1st Lt. Chris Dale said. 

State Patrol Cpl. Luke Mize said a CW Matthews F550 truck pulling a utility trailer was sitting on Browns Bridge Road with part of the vehicle in the center turning lane and another part in the left southbound lane.

At the same time, Mario Rodriguez Casto, 30, of Gainesville, was driving southbound on Browns Bridge Road in the left lane.

Gabrie Torres De Arellano, 34, of Gainesville, was headed northbound in the left-hand lane.

Mize said Castro’s vehicle hit the back of the trailer, causing the trailer to rotate counterclockwise and stop with the trailer’s front end in the northbound lefthand lane.

“(Torres De Arellano’s car) was unable to get stopped in time and struck the front of the trailer with its front end,” Mize wrote in an email.

Mize said Venable was standing in the center turning lane talking to Dario Triana, 21, of Marietta, who was driving the vehicle with the utility trailer.

“When (Castro’s car) struck (the utility trailer), an unknown object from (the utility trailer) struck (Venable) in the head,” Mize wrote in an email.

The only other person with noted injuries was Castro’s back seat passenger, Gabriela Hernandez-Arza, 48, who also was transported to Northeast Georgia Medical Center with head injuries.
