Dog the Bounty Hunter star Duane Chapman’s stepson Gregory Zecca is a passionate gun enthusiast who passed down the controversial hobby to his teenage son Anthony Zecca before his tragic shooting death.

Zecca accidentally shot and killed his 13-year-old son in their apartment in Naples, FL on Saturday, according to TMZ.

Little Anthony was only nine years old when the 38-year-old bounty hunter taught him how to use a rifle at Franktown Firearms Shooting Center in Franktown, Colorado, back in 2021.

‘Getting some range time in with our buddies @franktownfirearms,’ Gregory boasted in his Instagram account, which appears to have been disabled later on Sunday evening.

Local law enforcement confirmed to the outlet that they ‘responded to a call about the shooting around 8 p.m. ET’ but they’re calling it an ‘isolated incident’ and no arrests have been made.

Duane’s sixth wife Francie Chapman welcomed Gregory during a prior marriage, and Anthony’s mother is Alexandria Lane.

Little Anthony was only nine years old when the 38-year-old bounty hunter (pictured in 2021) taught him how to use a rifle at Franktown Firearms Shooting Center in Franktown, Colorado, back in 2021

The 72-year-old reality star and his 56-year-old wife — his sixth — addressed the terrible loss in a statement: ‘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.’

One year ago, little Anthony spent the summer with his grandparents and told a story about how he felt the wind of the Holy Spirit while visiting his ‘Meemaw’ in the hospital ER in 2023 after she injured her ankle.

Anthony and Duane sat on a bench in the waiting room when he suddenly felt a gush of cold wind blowing in from outside even though it was a warm, rainy day.

‘When we’re walking to her room I feel the wind again but from a different direction. When it first came, it hit me [on my chest]. But when it came again, it hit me from the back,’ the Christian child marveled.

‘And I’m wondering what is this? Because the doors didn’t open this time, so why am I getting hit by wind? [It was] the Holy Spirit. And I asked Meemaw and she said, “It was the Holy Spirit.”‘

Francie had been feeling miserable but ‘after X-rays and after we prayed, we go back into the room and she’s just fine. She said, “This don’t even hurt anymore.” And it turned out to not be broken.’

Aside from artillery and Jesus, little Anthony also enjoyed dancing to Usher and Diana Ross, he loved Busch Gardens theme park, and once excitedly met Predator at Duke City Comic Con.

The Chapmans — who began dating in 2020 — first bonded over their shared grief about being widowed.

Duane suffered the loss of his fifth wife Beth Smith in 2019 to stage II throat cancer and Francie suffered the loss of her husband Bob Frane in 2018.

Duane – who’s fostered gun culture in his family/team – first found fame starring in A&E reality show Dog the Bounty Hunter, which aired for eight seasons spanning 2004-2012 and spawned three spin-offs (pictured in 2023)

‘We understood the pain that the other one was feeling, and [in] those tough days and moments, we helped each other stand up,’ she told ET in 2020.

‘We could cry with each other and talk about what we were feeling. We were able to walk alongside each other through the pain and heartbreak, and it brought us together in this amazing way.’

The mourning couple will celebrate their fourth wedding anniversary on September 2.

On November 15, the Chapmans will host their 3rd Annual F.U.S.E. Restored Gala in Cape Coral, FL.

The old Hollywood glam-themed human trafficking benefit will be held at The Westin of Cape Coral at Marina Village.
