A heartbreaking tragedy has struck Duane "Dog the Bounty Hunter" Chapman and his wife Francie. On Saturday night, 13-year-old Anthony Zecca, Francie's grandson and Duane's step-grandson, was accidentally shot and killed by his own father, Gregory Zecca, in their Naples, Florida apartment, according to TMZ. Gregory, 38 — Francie’s son from a previous marriage — reportedly works alongside Duane in his bounty hunting operation. Authorities labeled the shooting a “freak accident” and an “isolated incident.” No arrests have been made. In a joint statement, Duane and Francie said: “We are grieving as a family over this incomprehensible tragic accident and would ask for continued prayers as we grieve the loss of our beloved grandson, Anthony.”
