A family is facing tragedy after a five-month-old baby boy was horrifically killed by a dog in South Carolina.

Dean Everett Gross was described as a ‘bright spirit’ before he was mauled by a dog on Thursday and left in intensive care for 24 hours before succumbing to his injuries.

The baby boy’s parents, Thomas and Natalie Gross, described him as a ‘treasure of their lives,’ according to a GoFundMe.

‘Dearly loved, wonderful in so many way, [Dean] brought endless joy to everyone who knew him,’ the page said.

‘Dean’s bright spirit and sweet presence touched the hearts of his family and friends every single day.’

The Anderson County Sheriff’s Office responded to reports of a dog attack at around 1pm on May 14, as Dean and another adult were left injured before the dog fled the home.

It is unclear what breed the dog was and who owned it.

According to the Fox Carolina, police said the dog was eventually found and captured near Cater’s Lake and was handed over to Anderson County PAWS.

Officials confirmed to the outlet that Dean sustained critical and life-threatening injuries and was flown by light flight to Greenville, where he died on Friday.

The Anderson County Coroner’s Office said that Dean died from multiple traumatic injuries, and ruled his death an accident.

Officials said that the adult sustained serious injuries, but was later released. The identity of the injured adult remains unclear.

‘None of us are doing well but we are together as a family in tears and love,’ the fundraiser, which has garnered over $44,800 as of Monday afternoon, continued.

Thomas Gross’s brother, Miller Gross, wrote on Facebook: ‘My sweet little brother and sister in law lost a true little angel to a terrible unthinkable tragedy.’

‘Dean was such a sweet and happy little guy,’ he continued. ‘I feel so grateful to have gotten to be his uncle for five months.’
