MESA, AZ -- The Maricopa County Sheriff's Office is investigating a possible case of bestiality involving a fire chief.
A fire chief with the Mesa Fire Department faces misdemeanor criminal trespassing and public sexual indecency charges.
Authorities say the chief knocked on the door of a 13-yr-old girl staying home alone for the weekend, but when she didn't answer, he went into the backyard and took a lamb into a nearby barn.
"One could certainly ascertain that if you're in a barn and in a secluded area with a lamb, and you're behind her and your pants are down by your ankles, then an unnatural sex act is probably occurring," said Lisa Allen of the Maricopa County Sheriff's Office.
The chief is on administrative leave pending the investigation.
Many of his co-workers are shocked about the arrest, saying the chief has been an exemplrary employee for the past 26 years.
