State police say they found three dogs hanging and burned over a pile of burning tires in Fayette County.
Police say the dogs were found about 5 a.m. Thursday in Redstone Township hanging by ropes from a tree.
Theresa Linden, manager with the Fayette County Humane Society, says officials don't know if the dogs were alive when they were hanged.
Linden says authorities also found the image of a pentagram on the ground, a five-pointed star commonly associated with Satanism.
The back of one dog was burned off. Another had puncture wounds to its neck.
Authorities believe more than one person was involved because the dogs were heavy. One weighed about 75 pounds.
