Chester police say the vehicle was parked at a gas pump at the Eagle Save Mart just after 10 a.m. Tuesday. Witnesses say the children’s father was outside of the car when, according to officials, a 2-year-old boy was handling a gun inside of the car and it discharged.

The bullet struck a 4-year-old girl who was also sitting inside.

People on the scene immediately rushed her to the hospital, which is just over a half-mile away from the scene.

Witnesses struck by the tragedy say the children were always with their dad.

“It was a morning ritual, I’d see them every morning,” Theodore Thaddeus Crump said. “He was a good dude. He went to work everyday. He kept his kids right there beside him. It’s the number one thing that he did, OK. Their dad was a very beautiful man.”
