Years ago we would never believe this sort of thing happening yet not only is it happening but is increasing.
I know people say satan is behind this but people still have free will especially those who know God and have walked with him. This man's pastor vouches for him.
On some occasions the person may be a hypocrite, living a secret life and hiding it from everyone but there have been others who murder and suicide and there isn't any secret sinful lifestyle.
It's horrific and obviously God knows why but what causes a person to go that extreme and not try to get help
