Reports so far are that Adkisson had no connection with TVUUC and had never been there before.
Greg McKendry, the usher who was killed, was reported to have interposed himself between Adkisson and the congregation. May he rest in peace, and may all who loved him be comforted.
I am not a member of TVUUC, but it's close to where I work and I know a number of the members. One of my coworkers was there today with his wife and daughter, who was performing in the play. They have reported that they are all uninjured.
