MARICOPA COUNTY, Ariz. (CBS12) -- A retired UPS driver from Washington state is accused of wanting to have sex with his neighbor's farm animals in Arizona.

The Maricopa County Sheriff's Office arrested 56-year-old James Allen Darland on a felony charge of conspiracy to commit bestiality.

Investigators say Darland told undercover detectives posing as farmers that he wanted to have sex with various animals on the farmer's property, including with miniature horses, dogs and goats.

The Sheriff's Office said Darlard admitted to having sex with his neighbor's horse, dogs and sheep while he lived in Washington.

Authorities also say Darland, while driving for UPS, admitted to having sex with the pets of his customers when they weren't home.  Darland, according to the Maricopa County Sheriff's Office's Facebook page, picked up stray dogs to have sex with as well.

Investigators seized Darland's dog.  The suspect said he had sex with his own dog.  The animal is now being cared for and evaluated for any signs of sexual abuse by the Arizona Humane Society.
