A motorcycle driver and his passenger were killed Saturday night when they were struck from behind at a red light on U.S. 19 in Hudson, authorities said.

Jaime Hernandez, 50, of Belleview and Lori Ann Gestring, 50, of Spring Hill were headed north on U.S. 19 and waiting for a green light at New York Avenue around 11:15 p.m. when a vehicle behind them failed to stop.

That vehicle, a 1992 Ford truck driven by 30-year-old Joshua Stalker of Lamont, slammed into the back of the 2011 Yamaha, wedging it under the car's front bumper. The motorcycle caught fire, and both riders died at the scene, the Florida Highway Patrol said.

No charges have been filed against Stalker, but the case remains under investigation, the FHP said. Stalker suffered minor injuries.

There was a separate but related crash in the same area. A Pasco County sheriff's deputy was standing outside his patrol car directing traffic around the crash when the car was struck by a northbound vehicle. There was significant damage to both vehicles, but no one was injured, the FHP said.
