Lab results have connected one of three black bears killed by wildlife officers in southwest Florida to a fatal attack on a man and his dog a day earlier, officials said Friday.

New information on Florida’s first fatal bear attack revealed the culprit was a 263-pound black bear that broke into the man’s home and killed him and a dog, wildlife officials said. The male bear tested negative for rabies, the Florida Fish and Wildlife Conservation Commission said May 9.

The Florida Fish and Wildlife Conservation Commission has concluded its initial investigation into what is now confirmed be the first fatal black bear attack in the state.
