The driver involved, 52-year-old Jose Guadalupe Hernandez, initially survived but succumbed to his injuries overnight after being rushed to a local hospital

Six people including two parents and their three children are dead after a train crashed into their Escalade SUV as it went over a railroad crossing in Florida.

The incident happened on Saturday at a private crossing roughly 20 miles west of Tampa, where there is no barrier and only a stop sign warns of the chance of a passing train. It left five of the vehicle's seven passengers dead at the scene.

The seven people in the SUV were on their way to a quinceañera, a party celebrating a girl's 15th birthday, when they encountered a railroad crossing marked by a stop sign and a railroad crossing sign, but no crossing arms or warning bell in Plant City, Florida, according to Hillsborough County Sheriff Chad Chronister.

The victims were a man, two women and three children, and another man was injured in critical condition on Sunday, officials said. They were members of a family and two friends.

The driver 52-year-old Jose Guadalupe Hernandez initially survived, but succumbed to his injuries overnight after being rushed to a local hospital, cops said.

50-year-old Hernandez's wife Enedalia, and three children - Julian, 9, Alyssa, 17, and Anaelia, 22 - were ejected from the back of the vehicle upon impact and were all killed. Cops say the car 'crawled across the railroad crossing' but 'never stopped to look both ways.'

The Hillsborough County Sheriff's Office is heartbroken to share the latest update regarding the fatal train versus vehicle crash investigation,' a spokesperson for the office said.

'The driver involved in the crash succumbed to his injuries and passed away overnight.'

'[Hernandez] was driving his white 2020 Cadillac Escalade southbound on Jim Lefler Circle from US Highway 92, approaching a railroad crossing controlled by a stop sign and a railroad crossing sign,' officers wrote.

Hernandez had six other passengers in the Escalade, including his wife, two juvenile children, an adult child, and two friends of the children.

'For unknown and undetermined reasons, the driver slowly crossed the tracks directly in the train's path. 

'Five rear passengers were ejected from the Escalade as it rotated and rolled to final rest.

He added that 'the train conductor did everything he could to slow this train down,' signaling loud horns and flashing lights, but failed to avoid the vehicle.

A witness told deputies he honked his horn to get the driver's attention, as he crossed the little-traveled crossing to bring the passengers to a birthday party located just across the tracks.

The SUV, the sheriff said, 'flipped violently several times' before it landed a distance away from the crossing - which has no barrier and only a sign indicating that trains may pass at any point.

Jakub Lopez, 17, who was  a friend of one of the siblings also died in the crash. Guillermo Gama, 23, Anaelia's boyfriend who was a passenger in the front of the car, is the sole survivor and is in critical condition at Lakeland hospital.
