I recall what you might be remembering. But it appears DK was not a regular church attendee and in all fairness, the Pastor only made the comment about not being sure how to go about evicting someone
after the shootings occurred. That's absolutely normal way to reflect his regret, given the church was his responsibility.
Furthermore the Harvest Festival was held by the church and notice nobody said that DK was told he was unwelcome. In the quote above the Pastor told the County Sheriff that DK's behaviour didn't raise any alarms. If the Pastor didn't notice strange behaviour, then to your earlier comment, he'd have no reason to post armed security guards at the church doors.
ETA from the same link (not sure if you read this):
"The mother-in-law, Michelle Shields, told Read she was so excited to see Kelley there voluntarily with her grandchildren."

If that is true, in my opinion something significant must've occured between Oct 31st and Nov 5th.
