The suspect is described as a white male with balding gray hair, 50 to 60 years old, about 6 feet tall and weighing approximately 280 pounds.

The suspect was driving a 1996 to 2000 silver or gray Dodge Caravan with an off-color rear bumper. At the time of the incident, the van had two bicycles on a rear bike rack.

“This little dog endured an agonizing, terrifying death when his head was bashed against the sidewalk by a disturbed and violent man,” says PETA Senior Vice President Lisa Lange. “PETA is urging anyone with information about this man to come forward now so that he can be held accountable for his crimes and stopped from hurting anyone else.”

Perpetrators of violent acts against animals are often repeat offenders who pose a serious threat to all animals—including humans.
