A Canandaigua mother and son are demanding to know why a hit-and-run driver deliberately rammed into them with his car.

Michelle and Cory Martino say they were bicycling on Brickhouse Road Saturday when a car passed them, stopped, backed up straight at them and knocked Cory over, then took off.

State troopers have released pictures and video of the suspected vehicle.

They're looking for a gray four-door sedan possibly an older model Pontiac with a yellow sticker on it.

The Martino's say what happened remains a scary mystery.

"He backed up towards us and I'm like 'oh my what is he doing?' and I realized in a split second that he was aiming towards us and, next thing I know, my sons flying off his bike," explained Michelle Martino. "He hit the ground so hard he cracked his helmet."

Cory Martino said, "It was a very deliberate act. Him slamming on his brakes hard enough that they squealed and flooring it again it backwards at us, not stopping before you hit me… is why I am thinking it's a road rage."

Cory Martino was taken to the hospital with minor injuries and now he says he's just sore.

He says he knows of no enemies who might want to do this.

Cory added that he and his mom might start looking for bike paths in the future.
