[Warning: Potentially Triggering Content] Oh, no. Dog the Bounty Hunter's family is grieving a nightmarish loss... Dog's step-grandson was just shot and killed - allegedly accidentally by his own father! Heartbreaking. Sources told TMZ on Sunday that the horrific incident occurred on Saturday night in Naples, Florida, at their apartment. Gregory Zecca, the son of Dog's wife Francie (from a previous marriage), allegedly shot his 13-year-old son Anthony in a freak accident. Jeez. In the apartment?? What happened? Right now, it's unclear. But it had deadly consequences. So devastating.
