Carlton Freeman, who lost both of his legs to diabetes years ago, was "minding his own business going down the side of the road" in his wheelchair when a pack of dogs attacked him, Chris Nisbet, a coroner, told ABC News 4 in Charleston, S.C.

The May 8 attack killed the 80-year-old previously-paralyzed amputee, according to the Tuesday news report. Nisbet told ABC that Freeman was "pulled from his wheelchair by his legs as he tried to fight off the dogs” who were biting him and tearing his clothes. He was rushed to the hospital, where he died on Monday after succumbing to his wounds.

Nisbet revealed that he was shocked the Harleyville, S.C., senior citizen lived as long as he did. "Upon my examination of Mr. Freeman, it is a wonder that this gentleman was able to hang on as long as he did," said Nisbet in a press release. "He had bites and lacerations from his legs to the top of his head. This is very sad story, but even worse that Mr. Freeman was basically helpless to the attack, due to being a bi-lateral amputee."

It wasn’t stated what types of dogs were responsible for Freeman’s death, but comments on ABC’s story suggested they were pit bulls.

Animal control was able to capture three of the dogs, but is still looking for the fourth, ABC News 4 wrote. A report from the Dorchester County Sheriff's Office said the dogs had been roaming the streets for months. Neighbors told investigators they suspected the animals belonged to neighbor Barbara Goodwin.

Deputies were able to catch two of the dogs, the mother and one puppy, both of which had blood on their fur, the report said.
