Authorities are investigating two deadly truck crashes that happened less than 24 hours apart.

Both accidents occurred in Pike County, about 48 miles south of downtown Atlanta.

In the first, a commercial logging truck overturned while traveling eastbound on Ga. 18 just before 2:40 p.m. Wednesday. The driver, Ricky Lovejoy of Greenville, died on the scene, according to the Pike County Sheriff’s Office.

“The initial investigation has shown that the truck left the roadway for an unknown reason and then turned over after striking a ditch,” authorities said in a Facebook post.

The second accident happened just before 6 a.m. Thursday on Caldwell Road near Flat Rock Church Road. A pickup truck collided with a garbage truck, the sheriff’s office said.

Pickup truck driver Matthew Williams, 18, of Zebulon, died on the scene.

“Traffic investigators are working to determine the underlying causes of both of these tragedies,” authorities said.
