Collier County Sheriff's reports indicate child died of gunshot wound to neck, while TMZ links child to Dog The Bounty Hunter

Dog the Bounty Hunter’s stepson, Gregory Zecca, who fatally shot his 13-year-old son in a “freak accident” at their Florida home Saturday, is on a psychiatric hold amid fears he could take his own life.

Police are still looking into the shooting death of a juvenile in Florida who is reported to be the step-grandson of Duane "Dog" Chapman. A spokesperson for the Collier County Sheriff's Office told ABC News Tuesday that the investigation is ongoing into the July 19 shooting at a residence in Naples, Florida.
