Duane “Dog” Chapman’s stepson reportedly shot and killed his 13-year-old son over the weekend.

TMZ was the first to report that Gregory Zecca, who is the son of Chapman’s wife, Francie, shot his son Anthony in an accident. The incident reportedly took place Saturday night at an apartment in Naples, Florida.

“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,” Chapman and his wife said in a statement given to TMZ. They also asked for privacy as they mourn Anthony.

Police told TMZ that they responded to a call about a shooting around 8 p.m. local time. No arrests have been made, with police saying it was an “isolated incident.” An investigation is ongoing.

Zecca, who is Francie’s son from her previous marriage, works with Chapman on his bounty hunting team, according to TMZ. Chapman and Francie got married in 2021 after their respective spouses died.

Chapman gained fame when he starred on Dog the Bounty Hunter, which ran for eight seasons from 2004-12. It also featured his late wife, Beth Chapman, along with other family members.

The couple went on to star in another show, Dog and Beth: On the Hunt, which aired on CMT for three seasons, from 2013-15. 

After that, they appeared in Dog’s Most Wanted for WGN America. That show aired for one season, in 2019.
