In the past week two Pennsylvania man have been booked in bizarre animal cases.

Michael Crawford, 68, of Western Pa., was arrested Monday in Arizona after he traveled there from his hometown in to perform oral sex on a horse. 

Undercover deputies from the Maricopa County Sheriff's office met Crawford with two miniature horses in a trailer.

After Crawford picked a horse for sex, he was arrested on bestiality charges. He confessed that he has traveled the country since the 1970s seeking horse-owners who will allow him to have sex with the animals.

"Perversion has reached a new level," Maricopa County Sheriff Joe Arpaio said in a statement.

Meanwhile, just days before, a Lancaster County man was charged for an incident in which he was found nude and drunk in a hog barn in Millersville, Pa.

Larry William Henry, 65, told police who caught him after 10 p.m. on June 26 that he had drunk a six-pack of Hamm's Beer, and said "I just like pigs," reports say.

It is not known if he was trying to have sex with the pigs, and why he was nude.

Henry was charged with trespassing, indecent exposure and public drunkeness, police said.

Bestiality is a serious crime against animals, said a PETA (People for the Ethical Treatment of Animals) representative.

"Bestiality is viewed with revulsion in the US and the people who engage in it are consider amoral deranged and pathetic, because they are," said Kristin DeJournett, a cruelty case work manager for PETA.

Bestiality is "unnatural and confusing" to animals, DeJournett said.

"Bestiality is illegal in most states on moral grounds and it can also easily violate anticruelty laws in all of the staes ... because the animals are commonly internally injured and thats often fatal."

DeJournett also noted that studies link bestiality with penile cancer, and also show that sexual assault is more commonly committed by human practitioners of bestiality.
