A central Florida woman who fatally shot her 20-year-old son then killed herself at a shooting range left recorded messages that said she was the anti-Christ and that she needed to save her son.

In rambling, teary audio recordings left for her boyfriend and authorities, as well as shorter suicide notes, Marie Moore, 44, apologized several times and said repeatedly: “I had to send my son to heaven and myself to Hell.”

Authorities said Wednesday they still had no motive for the murder-suicide that shocked fellow customers and employees at the Shoot Straight range in Casselberry, north of Orlando, on Sunday.
