Maricopa County Sheriff's Office deputies arrested three people Monday on suspicion of using Craigslist to find a dog for one of them to have sex with.
Deputies arrested San Tan Valley residents Sarah Dae Walker, 33, and Shane Walker, 38, on charges of conspiring to commit an act of bestiality. Officers also arrested 29-year-old Robert Aucker of Gilbert.
According to the Sheriff's Office, the three suspects used Craigslist to find a male golden shepherd for Sarah Walker to have sex with, while the other two would look on.
All three told detectives that they were going to commit an act of bestiality, the Sheriff's Office said.
The Walkers said they are "swingers" who engage in an "open marriage," according to detectives.
According to detectives, the three suspects drove to a prearranged location intending to commit bestiality with the dog.
The owner of the golden shepherd was an undercover detective, according to the Sheriff's Office.
Aucker told detectives he had a sexual relationship with Sarah Walker for about a month. She reportedly told him that she had dreams about having sex with a dog, the Sheriff's Office said.
"People who do this for enjoyment are a different breed, that's for certain," Maricopa County Sheriff Joe Arpaio said.
Arpaio criticized Craigslist executives for failing to put a stop to such advertising.
Bestiality is a class 6 felony.
