Six Flags Over Georgia temporarily closed its "Goliath" roller coaster for maintenance due to a wasp's nest just hours before a teacher fatally fell from the ride, a parkgoer told The Post.

Hassan Kariem, 42, died and four children were injured when he was ejected from the high-speed hypercoaster shortly before 4 p.m. on Monday at the park near Atlanta. The Cobb County Police Department's Major Crimes Unit and Georgia's Office of the Commissioner of Insurance and Safety Fire are investigating the incident.

Two teachers who were at the park told The Post they attempted to ride Goliath approximately three hours before the fatal incident but were unable to because the ride was closed for maintenance. A park worker was reportedly conducting a test run at the time.

"I was there at the same time, and the ride op told me the ride was down because of a wasp nest," said Renee Byrd, a coaster enthusiast from Valdosta. Byrd, who later rode Goliath about 20 minutes before the accident, stated she did not see any wasps during her ride.

Byrd, who has ridden Goliath hundreds of times, suggested that the unusual sounds and multiple restraint checks reported by riders on the coaster with Kariem might not be uncommon. "The ride ops have to unlock the entire row sometimes or multiple rows in one train when a large person’s restraint won’t click down all the way," she explained. "The clicking and unlocking was making sure the large guest’s restraint locked, and every time it un-clicks for the other guests."

Six Flags Over Georgia is scheduled to reopen on Friday at 6 p.m., but Goliath will remain closed. Police stated that Kariem was found unresponsive and not breathing beneath the ride after being dispatched to the park around 3:58 p.m. on Monday. An incident report indicated that the victim was discovered on a building within the park near an inner service road.

Kariem, an Atlanta teacher, was at the park with his family to celebrate his niece's 13th birthday and was seated next to her when he fell. His fiancée's brother, Joshua Nelson, told CNN that Kariem's "final moments and words were with her." Nelson stated that his niece called him crying after the ride concluded to report that Mr. Hassan had fallen off.
