Four individuals, including two seniors and two younger adults, were found dead in a New Hampshire home on Christmas Day, suspected to be victims of carbon monoxide poisoning. Authorities responded to a welfare check after family members expressed concern, noting the absence of the individuals at a holiday gathering. Investigations indicate the deaths may be accidental, linked to the home’s gas heating system, as there were no carbon monoxide detectors present. Autopsies are scheduled to confirm the causes of death.
