Authorities are investigating a tragic incident in Madbury, New Hampshire, where two adults and two children were found dead in what officials are describing as an apparent murder-suicide. A third child, a toddler, was discovered alive and unharmed at the scene. The New Hampshire Attorney General's office has confirmed the deaths and is leading the investigation. The case has drawn attention as a family tragedy involving multiple fatalities. There are separate reports of a fire in Peabody, Massachusetts, that displaced 15 people, including eight adults and seven children, but this incident is unrelated to the New Hampshire case.
