One of these Mormons, Alma Dayer LeBaron, Sr., moved his family, which included his two wives and eight children, to northern Mexico in 1924.

[5] The group ultimately numbered around thirty families who lived in both Utah and a community called "Los Molinos" on the Baja California Peninsula.

In 1972, the LeBaron sect suffered a schism when Ervil fell out with Joel and started the Church of the First Born of the Lamb of God in San Diego, California.

[3][6] Leadership of the Baja California church passed to the youngest LeBaron brother, Verlan, whom Ervil tried to have killed over the next decade.

[11] In 1977, LeBaron ordered the killing of Rulon C. Allred, leader of the Apostolic United Brethren, another Mormon fundamentalist sect.

His 10th wife, Vonda White, was convicted and sentenced to life in prison for the murder of Dean Grover Vest, one of LeBaron's henchmen, who had attempted to leave the church.

Ervil LeBaron has also been linked to the death of his own 17-year-old daughter Rebecca, who was pregnant with her second child and hoped to leave the group; it is alleged that his stepson Eddie Marston and brother-in-law Duane Chynoweth strangled her in April 1977.

[20][21] On June 1, 1979, Ervil LeBaron was apprehended by police in Mexico and extradited to the United States, where he was convicted of having ordered Allred's death.

[3] Eddie Marston, one of LeBaron's stepsons and former thugs, was killed in the same manner, and Mark Chynoweth, a father of six, was shot multiple times in his office in Houston, Texas.

Probation Officer about her supervised release states that Jacqueline Tarsa LeBaron had not made any payment toward the $134,000 restitution imposed by the Court; simultaneously, the officer's report states that she "has severe mental health issues" including mania requiring psychotropic medication and which have led her to seek Social Security Disability Insurance.
