Yep, an elder in my lasy cong, mid 40's, been with his wife since high school, gave talks on marriage etc and talk on dc. They had no kids and couldn't conceive so he put her thru ivf to make babies. She had two girls, and all the time he was making family with his wife he had a woman on the side, and she even came to the dc to hear his talk. He also embezzled from the contribution box, and a sister caught him but they disfellowshipped her for lying...and he swore like a trooper at his work and embezzled there as well. He lost that job but got another.
Eventually be was caught after 5 years with the other woman while his kids were about 2and 4...dfd. rocked the congregation. I had also known an elder and Pioneer who had been the exemplary family always interviewed who had been conning brothers... Got stepped down as elder but not dfd, moved interstate. Made me start wondering if the whole org was rotten in the core like these two creeps, and boy was I right.
