Only ever heard of one local horse stealing —pasture along the rural road with a gate ON the road (fastened but no lock). Horses pastured with halters on (another bad idea, I think) Only 7 miles from our local horse auction (not New Holland --an Amish sale barn).
Someone pulled in a trailer, loaded the horses and took them to the auction.
The owner, a teenager and her boyfriend, suspected the destination and went to the auction where they found the horses and had the thieves arrested. Both sets of parents were lawyers, one quite prominent in politics and civic organizations. I doubt the perps did jail time (don’t know for sure), but do know they were taken to court . . .probably pled out.
This was all 20 years ago …
