Pennsylvania state police served a search warrant Saturday after reports of animal abuse in Clearfield County which has been going on for up to five years.

District attorney Bill Shaw told them the charges so far are part of an ongoing investigation into the abuse of animals.

He said: “This is an unpleasant topic, but the facts are that we received a report of folks having sexual intercourse with animals, farm animals.”

On Saturday morning, state police raided a rural home in the small town of Munson where they found the sick trio.

The men are accused of having sexual relations with at least nine female horses, a cow, a goat, and dogs, at a property on Mouse Road.

Police also recovered several semi-automatic weapons at the home.

A teenage boy was also present at the home and was reportedly used to hold the animals during the sex sessions and they are set to be additionally charged with endangering the welfare of a child, and the corruption of a minor.

The statistics of alleged abuse is staggering, said police.

They face charges including 1,460 counts of sexual intercourse with an animal, and 1,460 counts of cruelty to animals, reports WTAJ.

Mr Shaw told the station: “So I’ve been doing this for over 20 years and this is probably the worse situation of this type of case that I’ve come across.”

It is a makeshift farm involved, said police.
