I've heard rumors of this person's existence for a while, but a fellow dog owner has now decided to put a stop to it:
According to reports, the owner allows his pitbull mix off lease at all hours, and encourages it to attack other dogs.
He then joins his dog in the fight, by kicking the other other dog and stabbing it with an ice pick he carries.
He sometimes carries a cane or umbrella and uses it to hit the other dog and owner.
Do not confront this person. Call 911 or the 78th Pct. A warrant is out for his arrest.
