Overview
Three people were found dead and a fourth hospitalized after responders entered a Mountainair, New Mexico, home on May 20, officials said.
Several first responders later developed coughing, vomiting and dizziness, prompting hazmat decontamination at a hospital, state police and hospital officials said.
Mountainair Mayor Peter Nieto said drugs were found at the house, and Albuquerque Fire Rescue Hazmat teams and state police are testing to identify the substance.
Authorities said roughly 18 to 23 people, mostly first responders, were decontaminated and checked, and that two people remained in a hospital, officials said.
Investigators said autopsies and laboratory tests are pending and that they do not believe the substance was airborne but may be transmitted through contact, officials said.
