On Monday, six people, including five teenagers, were found dead in rural Oklahoma in what is believed to be a murder-suicide. The shooter, Jesse McFadden, was a 39-year-old convicted sex offender who was on trial for child pornography charges. The victims included his wife and her three children, as well as two of their friends. The investigation is ongoing, and authorities are trying to understand why McFadden was free while awaiting trial on new sex charges.
