It was just a weird turn of events all the way around, and no one could piece anything together with the information they had gathered. They thought at first he might have committed suicide, which made everyone feel bad, but no one saw any signs. There were a few odd things that made them wonder if he had possibly been murdered. Once he was found unresponsive, their mom went deeper into dementia and has ever since. She went from a few episodes that made them get her tested to full-on, not being present most of the time. All three of the boys and even his three brothers have been very stressed for 11 months. To me it sounded like something from a CSI episode I watched once.
