CLAY COUNTY, Fla. -- The Florida Highway Patrol said a man and a woman were killed after a car crashed into the back of a school bus Tuesday afternoon in Middleburg.

The crash happened at the intersection of Hall Boree Road and Blanding Boulevard in southern Middleburg at about 3 p.m.

The FHP said Elisabeth Brantley, 19, who was driving the car, and Paul Bruchesky, 48, who was in the front passenger seat of the car, died in the crash. Samantha Brantley, 16, who was in the back seat of the car, was taken to Shands with non-life-threatening injuries and was in good condition Tuesday night.

The FHP said three children on the bus were taken to Orange Park Medical Center and one was taken to Shands with minor injuries. The children, who are between the ages of 10 and 12, were released later Tuesday evening.

FHP Lt. Bill Leeper said the Pontiac four-door car rear-ended the bus and caught fire after the bus was slowing to make a left turn. He said 22 Middleburg Elementary School students on the bus were evacuated safely.

"We're still trying to determine why the driver of the car didn't see the bus stopped," Leeper said. "(There were) not any skid marks, any evasive action prior to colliding with the bus, so obviously it didn't see it sitting there."

John Brantley, the father of the two girls in the car, said his daughters were traveling with Bruchesky to practice bowling for the Special Olympics in Orange Park.

The FHP said after the crash happened, the driver of a white pickup truck who saw the car on fire and wedged under the back of the school bus pushed his truck into the car to back it away from the bus.

The FHP said the driver, who is unknown and had already left the scene when troopers arrived, was trying to create space between the fire and the children on the bus.
