I’ve never been in a Catholic supply store so I can only imagine, but it must contain a whole lot of biblical merchandise strongly associated to religion in general, scripture, crosses and replicas of Christ etc. Even the private back room where he committed the crime, wall hangings, passages from the bible, ornaments associated to Christianity? I can’t help but think from the moment he walked in the door, he was literally surrounded by objects associated with God.
So I could be wrong, but because of that particular location he chose and his past religious training, pastor role and other employment associated with various churches, it’s as if he was violently lashing out at religion (god) and the innocent females he viciously attacked, assaulted, murdered were merely the means for him to do so.
If he has committed prior crimes, including rapes and homicide, this particular incident where he stood a high chance of getting caught seems it might have represented an violent finality to him, an horrific end of the road episode he intentionally orchestrated to get right up close in God’s face and indeed he was arrested.
