Police indicate the vehicle hit a guardrail and went airborne, landing upside down in about six feet of water.
Four onlookers dove into the water to rescue the man in the passenger seat while Franz was rescued by emergency officials arriving on the scene.
The good Samaritans used a rock to break open the vehicle’s window to rescue the passenger. The Huntington Fire Department rescuers used a hydraulic Hurst tool and cutters to remove Franz from the vehicle.
Both Franz and O’Mara were transported to Huntington Hospital. Franz was pronounced dead and O’Mara was treated for injuries and released.
An investigation is ongoing by detectives from the Suffolk County Police Department’s Second Squad. At the time of the incident, the road was wet from rain and the vehicle was on a curve while driving.
