3 dead in New Mexico and first responders treated for exposure to unknown substance, officials say
Investigators are working to identify the substance as 18 first responders were treated and quarantined after exposure at the home.
On Wednesday, New Mexico State Police reported three deaths and 18 first responders hospitalized in Mountainair after responding to a suspected overdose at a home east of Albuquerque.
Albuquerque Fire Rescue Hazmat teams assisted at the scene, where first responders experienced nausea and dizziness after contact with an unidentified substance during the emergency response.
All exposed individuals were transported to the University of New Mexico Hospital to be quarantined, evaluated, and monitored, with two first responders listed in serious condition.
Investigators believe the substance spreads through contact rather than being airborne, and authorities confirmed there is no threat to the public while securing the perimeter.
