Helen Radkey, a Salt Lake City-based independent researcher who has been looking into the Mormon practice of posthumous baptisms for two decades, said there are hundreds of examples of Jewish Holocaust victims being baptized in Mormon churches around the world since 2012. In a report released this week, she shared names of 20 such people who had been baptized. There are at least hundreds, probably more,” Radkey, a former Mormon who was excommunicated from the church in 1978, told JTA on Thursday.
