CRANSTON, R.I. -- (WBZ) -- Former Patriots defensive captain Jerod Mayo’s bulldog, reported missing earlier in the summer, has been found dead in a dog trainer’s home. That dog trainer, Amelia Ferreira, is now being charged with obstruction.

Wrentham Police posted about the mysterious circumstances surrounding the disappearance of "Knox" the English bulldog. They said the trainer lost track of Knox and he “simply vanished.” Police noted that English bulldogs aren’t built to run very far and his e-collar was found nearby.

The Rhode Island Society for the Prevention of Cruelty to Animals said Monday that authorities located the bulldog’s body at Ferreira's home. The group said the bulldog died while in Ferreira’s custody.

“Ferreira is being charged by the Cranston Police Department, with one count of Obstruction, for concealing evidence relevant to this investigation,” RISPCA said. “Evidence revealed that Ferreira has known the whereabouts of Knox’s deceased body for several weeks and intentionally concealed his body from authorities.”
