4 O'Clock murders
The 4 O'Clock murders were the coordinated shootings of four people at the same time on June 27, 1988, at three locations in Texas led by Mormon fundamentalist leader Heber LeBaron of the Church of the Firstborn. Heber was the successor as church leader to Ervil LeBaron of the similarly named Church of the First Born of the Lamb of God. Ervil had previously orchestrated the murder of several others he perceived as apostates. Authorities say the religious organizations were responsible for over 20 deaths over several decades.
Aaron LeBaron was sentenced to forty-five years in prison as the orchestrator of the murders. The assailants Heber LeBaron and Patricia LeBaron were given life in prison, while Douglas Lee Barlow served a five year sentence due to reaching a plea deal.
