As a member of the Reorganized Church of Jesus Christ of the Latter-Day Saints, Lundgren wielded total control over his six-family flock. He beat misbehaving children with poles, trained his followers for war and masturbated while naked female cult members danced around him. A man of strange appetites, Jeb7, as he liked to be called, enjoyed having excrement rubbed all over his body by his loving wife as he preached about the coming apocalypse.
In 1987 he settled with his cult in a fifteen-acre farm in rural Ohio. There, according to cult members, they were intending to meet God in the final days of planet Earth. However, God would be angry with the cult, due to "man's sins." Lundgren, a resourceful man, figured that if he sent five of his own, the Avery's (whom he considered the weakest family in the cult), before the "judgement bar," God would take out his anger on them.
The Avery family was thrown in a pit under the barn of the cult's ranch and were shot to death with a Colt 45 which, incidentally, Avery had paid for. After the killing Lungren and his family fled to what they called "The Wilderness" in Tucker County, West Virginia. By the fall of 1989 the group relocated to Jackson County, Missouri where things started to really fall apart.
On December 31, 1989, Larry Keith Johnson, (whose wife, Katheryn Renee Jackson was chosen by Lundgren as his "wife.") reported the murders to Larry Scott of ATF-Kansas City. Three days later the first body was uncovered, that of Dennis Leroy Avery. On January 7, 1990, Jeff Lundgren, his son Damon, and wife Alice were arrested in Room #29 of the Santa Fe Motel in National City, California. At the time of their arrest police and ATF agents found an arsenal of weapons tucked in the room with them. His wife and nineteen-year-old son received five consecutive life terms for the doomsday killings of the Avery family. Jeb7 was sentenced to death. The remaining cult members (except for Larry) were sentenced to various lengths of imprisonment.
