When asked about leaving a bucket for the child to use the bathroom, McIntyre allegedly said, "DCF told him that it was OK to do that."
Neighbors said they were shocked about the arrest.
"He was always nice and helpful," said Joe Buchman. "I'm really surprised and shocked."
Investigators have not released what the relationship is between McIntyre and the child.
The age of the child has not yet been released.
Deputies do not believe this was the first time the child had been left home alone.
