From the available information, it seems this guy was a stranger who shows up at a Wednesday night meeting at a black church, a meeting attended by very few church members. Very odd.
Do you wander in to black churches where no one knows you and sit in on meetings?
Do we know yet if he sat their quietly or held them hostage before killing them?
Extremely odd.
But that’s just how Christians are. If a stranger joins a Bible study, they tend to be welcoming.
