In October 2015, 19-year-old Lucas from Chadwicks, New York, died from injuries sustained during an hours-long 'counseling' session at his church, the Word of Life Christian Church in Chadwicks, Oneida County, New York. Both he and his 17-year old brother (who survived, albeit with severe injuries), were repeatedly beaten by parishioners during the session, and among those indicted in connection with the beating were Leonard's own parents and older sister.
 The Chadwicks Word of Life Christian Church reportedly started out as an ordinary Pentecostal church before becoming ever more cult-like after pastor Jerry Irwin retook control and began shaming and controlling other members. One of Irwin's relatives accused Lucas of having been involved in witchcraft and voodoo, but these accusations were refuted by police. Authorities have stated that the torture was instead prompted by Lucas' desire to leave the church.
 On the night of October 11, 2015, following a Sunday church meeting, Leonard was allegedly subject to an all-night counseling session in the church attended by about 30 parishioners, including his parents and older sister. The meeting was reportedly held after Leonard expressed a desire to leave the church. Lucas and his 17-year-old brother, Christopher, were allegedly beaten continuously. According to witness testimony, the session lasted 14 hours and ended when the parishioners thought Lucas was dead. Lucas died in hospital the next day. Autopsy results revealed "multiple contusions from blunt-force trauma to the torso and extremities", including blows to the genital area.
 A grand jury handed down indictments to Leonard's parents, Bruce and Deborah Leonard, for first-degree manslaughter; it also indicted four other church members, including Leonard's older sister, Sarah Ferguson. Animals subsequently rescued from Lucas' parents' house were found to have been living in neglect, and the house was foul-smelling and full of garbage.
 Neighbors described the church as isolated from the local community and as a cult, with one saying that "church members used to build fires on the roofs, and there was chanting and weird rituals", and that dogs howled all night inside the church but were never seen outside. Cult expert Rick Ross said "This is an old-school group...It’s typical in many ways. They’re very isolated, they've cocooned their members and homeschooled the children. Besides a web site to sell pedigree yorkies, they were very isolated. That’s a common characteristic in cults to make sure they are the only ones influencing the member’s judgements." A former member said that parents were routinely encouraged to beat their children as punishment for getting bad grades.
 Following the incident, the pastor of the unrelated Word Of Life Assembly of God Church in Baldwinsville, New York, began receiving threatening phone calls from people confusing his church with the one in Chadwicks. The Chadwicks church, despite being Pentecostal, is not affiliated with Assembly of God or any other denomination, and is not overseen by any larger organization.
 The townspeople held a prayer vigil outside the church on October 20. The organizers of the prayer vigil also called for Word of Life to be shut down.
 Lucas's surviving brother, Christopher Leonard, began testifying in court starting on October 21. He said that during the beating, he was punched in the stomach, then struck on the genitals and other parts of his body with a 4 feet (1.2 m) "whip" made from an electrical cord. Later on, he was forced to wear ear plugs and ear muffs, and to sit in a corner. He said the church's pastor, Tiffanie Irwin, was responsible for organizing the counseling session during which the beating took place. When he saw his brother lying motionless on the floor, Christopher attempted to give him CPR but stopped once he realized Lucas was dead.
 On October 23, a family court hearing was held to determine who should have custody of the Leonards' seven other underage children, aged between 2 and 15.
