Authorities say fentanyl and methamphetamine were found at a home where first responders became sick after answering a call about suspected overdoses in a rural New Mexico county. Three people who were found inside the house died. A fourth person who was in the house and one of the first responders who became sick were still being treated at a hospital Friday. A doctor who saw the first responders exhibiting symptoms — including vomiting and dizziness — said their symptoms most closely resembled fentanyl exposure. However, the investigation into how the exposure happened and what caused it was ongoing.
