Experts Identify Key Evidence in Six Flags Coaster Death Probe

Investigators are examining potential mechanical failures, restraint problems and maintenance issues after a fatal incident involving the Goliath roller coaster at Six Flags Over Georgia in Austell, Georgia, on Monday, October 12, 2026. The investigation into the death of 42-year-old Atlanta resident Hassan Jihad Ibn Kariem could also influence potential wrongful-death claims and broader ride safety reviews. Cobb County police said officers working at the park responded at approximately 3:58 p.m.

Monday and found Kariem beneath the attraction, unresponsive and not breathing. Preliminary information gathered from witness and employee interviews indicated that he was ejected from the coaster, struck other patrons and then fell beneath the ride. Police have not established what caused Kariem to leave the coaster during operation.

The investigation remains ongoing, and officials have not announced a definitive explanation for the incident.

Amusement ride safety consultant Ken Martin said investigators will need to reconstruct the ride's operation using electronic records, maintenance documentation and information about its restraint system. Computer records and sensor data could help establish the coaster's condition immediately before the incident.

Maintenance logs and inspection reports could also help determine whether a mechanical defect or maintenance issue contributed to the ejection. Investigators may additionally examine passenger restrictions and whether the attraction was operating as intended. Martin identified the restraint system as another important area of scrutiny. The fit of a restraint can vary according to a rider's height and body measurements, although he did not identify a specific cause for Kariem's ejection.

The consultant also called for inspections of similar attractions while the investigation continues. He urged officials to make the findings public so that any identified safety problems can be addressed. Legal questions could extend beyond the park itself, according to Nakia Martin, a senior attorney with the Taylor Law Firm. Potential defendants in a civil case could include the park's owner and operator, the ride's manufacturer or designer, and outside companies responsible for maintenance or inspections.

The attorney said determining responsibility would depend on the investigation's findings. Potential contributing factors could include restraint failure, a mechanical malfunction, inadequate maintenance or operator error, but none has been established as the cause of the incident. Preserving evidence will be important to evaluating any future legal claims, the attorney said.

Relevant materials could include ride telemetry, sensor records, maintenance logs, inspection reports and video footage. Kariem's family could potentially pursue a wrongful-death claim, according to the attorney. Any claims involving other people at the scene would depend on whether they sustained injuries and on the circumstances surrounding those injuries.
