There is a whole lot of talk going on about, an apparently infamous trainer based mostly out of Penn National Race Track. I thought his name sounded familiar and so I did a bit of research, and it turns out he owned Lucy before she was retired.
He is infamous and strongly disliked by the majority because of his poor record with horses dying under his care. It seems that perfectly sound, healthy, and successful race horses are bought by him and then the next thing you know, they're going 40mph down the back stretch on a broken leg. Apparently he has shipped significant amounts of horses directly to Canada on slaughter trucks from his farm, to avoid gaining unwanted attention by going through auctions.
Somehow Lucy managed to get out of there before she broke down and/or was shipped off to the slaughterhouse. Lucky girl.
Here's the COTH thread.
Here's where it says Lucy belonged to him.
