Keith Kiefer, Puppy Love Perv, Pleads Guilty to Charges He Used Craigslist to Solicit Sex With Dog

One of two men accused of using Craigslist to arrange a sexual tryst with a dog has pleaded guilty to conspiracy to commit bestiality.

Maricopa County Superior Court officials tell New Times that 47-year-old Keith Kiefer changed his plea this morning.

Kiefer was arrested in February after an investigation by the Maricopa County Sheriff's Office revealed that he and another man, Patrick Trejo, a 25-year-old music teacher at Raul H. Castro Middle School in Phoenix, were using Craigslist to try and find dog owners willing to offer up their pooches for sex.

It apparently didn't occur to the two men that for a small adoption fee they could have gone to their local animal shelter and picked up their own dog -- but maybe the two men just wanted to play the field.

An investigation into the Trejo and Kiefer began in December after Maricopa County sheriff's deputies "became aware" that people were using Craigslist to try and nail non-humans.

The two were arrested after they allegedly agreed to meet a dog and its owner at a hotel for sex. In reality, they met MCSO deputies who took them into custody.

Kiefer's sentencing is scheduled for June 21.
