From the ELCA's News Release:
Two of the victims – the Rev. Clementa Pinckney and the Rev. Daniel Simmons of Mother Emanuel African Methodist Episcopal Church in Charleston – were graduates of the Lutheran Theological Southern Seminary, an institution of Lenoir-Rhyne University in Hickory, N.C. The Columbia, S.C.-based seminary is one of eight ELCA seminaries; Lenoir-Rhyne is one of 26 ELCA colleges and universities.
“The suspected shooter is a member of an ELCA congregation. All of a sudden and for all of us, this is an intensely personal tragedy. One of our own is alleged to have shot and killed two who adopted us as their own,” said Eaton.
Someone asked on Facebook about the shooter's membership. No one, as of yet, has responded with any details.
