A crazed carjacker in California dragged an Army vet and beloved grandfather a half-mile to his death after speeding off in the 79-year-old’s car, police said.

James “Jim” Norman was vacuuming out the back of his Chevrolet Trailblazer at an ARCO gas station in Norco at around 12:30 p.m. Monday when Ryan Hewitt, 29, jumped into the front seat, according to cops.

Hewitt sped away with Norman desperately hanging onto the car’s backseat, police said.

Witnesses who saw the carjacking taking place called police.

“The caller reported witnessing a male entering the driver seat of a vehicle and driving away with the vehicle owner partially inside the rear seat,” police officials said.

Norman was eventually thrown from the car, according to cops.

Investigators found his crumpled body a half-mile from the gas station and just a few miles from his home. Paramedics rushed the septuagenarian to a nearby hospital but his injuries were too severe. He was pronounced dead at the hospital.

“I just hope he went quickly and I’m grateful for the people — and I hope to meet them — that surrounded him and protected his body so he wasn’t just out in the middle of the road,” Norman’s daughter, Nicole Lauritsen, told 7 ABC Eyewitness News.

Lauritsen also told the station that her father had plans to meet for a meal. She said she thinks the killer knew her father was clinging on for his life, but panicked and kept driving.
