Lauren Stuart, a married mother who worked as a model, is accused of murdering her husband and two adult children before killing herself in Keego Harbor, Michigan.

According to The Detroit Free Press, Stuart was shunned after leaving the Jehovah’s Witnesses sect, and some friends told the newspaper that the banishment may have triggered the 45-year-old woman to murder her entire family and take her own life.

Lauren Stuart, 45, was married to university employee Daniel Stuart, 47, and the couple had two adult children who also were killed: Steven, 27, and Bethany, 24.

According to The Detroit Free Press, Lauren Stuart and her husband “left the religion more than five years ago because of ‘doctrinal and social issues,'” a friend reported.

The newspaper reported that when “someone leaves the religion, a drastic shunning takes place: No one inside the religion, even parents, are allowed to speak to the departed again.” Friends told the newspaper that they believe the shunning contributed to Lauren Stuart’s actions.

A woman also made those claims in a video that circulated after the murders. You can watch it above. In it, she says, “You turned them away, you shunned them. Why? Because they wanted to raise their children as they saw fit.”

Fox2 says a woman named Joyce Taylor had an “outburst during Sunday services at the Jehovah’s Witness Kingdom Hall in Union Lake” that “was caught on camera.”

“They were the nicest people, they would give their shirt off their back,” she said to the television station, adding that she blamed religion for the deaths. Taylor said that Lauren Stuart had confided in her that she was pained by what happened when the family left it.

I love to draw most of all, but have become fond in other medias of graphic design, being able to use my art in my works I do. I’ve always loved art, usually doing my own little art projects when not doing work. I’m always trying to learn new techniques to improve my skills, watching better artists at work. My goal is to be able to make a living off of what I love doing- art.”
