CBS 2’s Pamela Jones reports.

Cathey Castro paints the tragic picture for every dog lover: the nightmare of how her terrier, “Skruffi”, got run over by an SUV rolling through an Edgewater park yesterday.

The scene was just off Lake Shore Drive near Foster Avenue. Police say gunfire from a white jeep kicked off chaos.

“I heard a bunch of crack, crack crack, which we thought were firecrackers, until we saw a car come barrelling at us with guns pointing out of it, shooting randomly,” Castro says.

She says she hid behind trash cans and watched the SUV make tracks, running right over another dog lover’s dachshund. When the craziness calmed, she found Skruffi dead.

“Her whole side of her head was completely bashed in,” Castro says.

Surveillance cameras at the nearby Park Tower Condominiums caught some of what happened.

Neighbors hope it will help police find suspects.

Castro says she doesn’t know the man who was walking the other dog that got hit.
