There was a similar situation in a school in Philadelphia a while back. (I remember because it was the elementary school my mother attended in the early 1940s.) That was reported as an “accident,” too, and then we never heard anything else.
I share your suspicions, when I read the headline I suspected
it was one of those “Turtle on top the fence post” situations.
Boy, this is so similar to an incident just like it a few years back. I’m sure I remember reading about on FR.
Creepy.
