PHOENIX -- Maricopa County sheriff's deputies arrested two men who allegedly used Craigslist to connect with dog owners in order to engage in bestiality.

The sheriff's office launched an undercover investigation in December after deputies became aware that a number of people were using Craigslist to communicate with others who are interested in bestiality.

"The investigation indicates that there is a secret language facilitated by Craigslist users in order to obscure their criminal plans," Sheriff Joe Arpaio said in a press release.

During the investigation, detectives used a fictitious email account to respond to posts on Craigslist. They reportedly sent and received emails from two men later determined to be Keith D. Kiefer, 47, and Patrick S. Trejo, 25.

According to the sheriff's office, Kiefer and Trejo on separate occasions posted ads requesting sexual contact with a dog.

Kiefer and Trejo each agreed to meet who they thought was a handler and a dog in local hotel rooms. Deputies took the suspects into custody after they arrived at the rooms.

Both men face charges of conspiracy to commit bestiality.

According to the sheriff's office, Kiefer is an unemployed handyman from Mesa and Trejo is a music teacher at Raul H. Castro Middle School near 79th Avenue and Thomas Road in Phoenix.

In a letter sent home to parents, Principal Sarah Hernandez said Trejo will be placed on administrative leave and will not be permitted to return to school, pending the outcome of the investigation by authorities and school staff.
