A trio on Craigslist looking for a dog to have sex with found a match earlier this year, with a guy offering up his male golden shepherd mix to complete the foursome. Unfortunately, for the three humans in the deal — Shane Walker, Sarah Walker, and Robert Aucker — the guy offering up the dog was an undercover detective with the Maricopa County Sheriff's Office. The trio's plan, according to the Sheriff's Office, was to use Craigslist to find the dog to "fornicate" with the woman, while her husband and friend watched. The detective eventually was also offered the "opportunity to join in on the act," although it's not clear exactly what his role would have been. At the time, Sheriff Joe Arpaio exclaimed, "People who do this for enjoyment are a different breed, that's for certain." The three humans in the busted foursome all eventually pleaded guilty to bestiality charges.
