Strange stuff.
At first glance, I wondered if this break-in also involved some sort of twisted satanic ritual. The perp broke into a church, brought a dog with them, vandalized the place, human and animal blood were found all over the place, and the dying dog was left behind. I could be making too much of these facts, or have an over-active imagination, but it all sounds a bit odd.

Wouldn’t surprise me.
Could be; but people are cruel. If we would stand up and punish those that are; we would have a lot less.
