There are still mysteries to untangle, but few would doubt that Bones lived the sort of life that no one would wish upon a dog.

Two years ago, the police found him covered in blood in a Manhattan apartment with a dead man who had teeth marks on his body. He was cleared and released to an animal advocacy group that found him to be sweet, and got him a new owner in Ohio.

Things seemed fine until the new owner, a woman who claimed special skills in caring for aggressive dogs, reported that her house had been burglarized in January, and Bones had been taken.

Then, this weekend, Bones, a dogo Argentino, was found in a shallow grave behind the woman’s house in Toledo.
