NUTLEY, N.J. — Police have solved the case of a mysterious gravestone that was found by a maintenance worker at a northern New Jersey bus terminal earlier this month.

NJ.com reports Nutley police announced Monday that the headstone, which noted the death of Max Ferreira, actually belonged to a Newark Rottweiler and not a child as was initially believed.

Detectives were able to match records at a local animal hospital to confirm that Max the dog was born on June 16, 1990, and died on Sept. 29, 1998, just as the stone reflected.

Police say records indicated the pet belonged to former Newark resident Agostino Ferreira, who died in 2005.

Police say it’s still unclear where Max is buried or how his headstone ended up at the terminal.
