Michael Crawford, 69, pleaded guilty in November to one count of conspiracy to commit bestiality under a deal with prosecutors after his arrest by sheriff’s detectives at a horse trailer in Tolleson, 12 miles (19.3 km) west of downtown Phoenix. Crawford was arrested last July in an undercover sting operation that began when a deputy responded to his online advertisement that detailed his sexual intentions.
