A woman told WBZ-TV she heard the fall. “I was sitting on the back porch and I heard this loud crash, and I said ‘somebody threw something from the window,” said Curlie Beauliere. “When I went down there, that’s when I saw him laying on the ground, bleeding and wasn’t responding. I called 911.”

According to sources, the boy had special needs and was being taken care of by his grandmother on Sunday.

“I really feel bad for the grandmother because he was in her presence when this happened. When you lose a child, it’s bad enough but when you leave them with somebody else and something happens to them, it’s even worse,” said Beauliere.
