ANTIOCH -- The two pit bulls that attacked and mauled 10-year-old Martinez resident Hunter Kilbourn in August have been euthanized after their owners decided not to appeal a city board's decision to have the dogs humanely put down.

Rodrick and Courtney De La Cruz had five calendar days to appeal the Antioch Administration Appeals Board's decision that the dogs, named Jewels and Duke, be euthanized but elected not to do so, according to their lawyer, Mark McLaughlin.

"They are just so upset by the whole thing and they just decided they could not fight it anymore," he said.

Hunter's mother, Melody Ralls, said she felt a great sense of closure with the news but that Hunter still has a ways to go in his recovery.

"I feel relieved and truly believe that with the dogs being put down, it is not only justice for Hunter but it also prevents another attack in the future," she said.

At a doctor's appointment Wednesday, Hunter learned he will need to have scalp revision surgery on the back of his head. He will also undergo laser, cosmetic and reconstructive surgery as well as massage therapy on his face.

The dogs were euthanized Tuesday after business hours, per the Antioch Animal Services.

A fundraiser is planned for the evening of Oct. 10 at McGah's Pub & Piano Bar in Danville to help Hunter's family pay his medical bills.

Hunter was visiting a friend in Antioch when the two dogs attacked him on Aug. 11. Hunter suffered a partially severed ear, serious lacerations to his face and the back of his head and bite marks on his arms.
