Ritualistic Animal Slaughter?

This morning coming home from the gym, turning onto my little street across from the Frida Kahlo park I saw what appeared to be a stuffed animal lying in the street. I slowed down to get a better look and realized it looked like a stuffed lamb--its body was much rounder than a dog, and it had this strange woolly coat. I thought that lamb roadkill was a strange thing to find here in the middle of Mexico City. Later Lucy told me that she had walked by it this morning, and the animal looked like a lamb except that it had a long tail. Apparently its head and feet had been cut off and then the animal had been dumped in the street. Very creepy. As Lucy said, "Nothing like this has ever happened around here before."
