A hazardous materials incident in a small central New Mexico community left three people dead and sent 18 first responders to the hospital after they were exposed to an unidentified substance during a suspected drug overdose response.
The incident began around 11:00 a.m. on Wednesday when the Torrance County Sheriff’s Office and local emergency personnel responded to a home on Hanlon Avenue in Mountainair, a rural town of fewer than 1,000 residents located southeast of Albuquerque. Upon entering the residence, emergency crews discovered four unresponsive individuals inside. Two were pronounced dead at the scene, and a third individual died a short time later.
As emergency personnel worked to treat the residents, those who had direct contact with the individuals or the interior of the home quickly began experiencing severe symptoms. Eyewitnesses and officials reported that the responding emergency medical technicians and firefighters began coughing, vomiting, and suffering from intense headaches, nausea, and dizziness.
A total of 25 people were ultimately exposed to the substance. This included 18 first responders from the Mountainair EMS and Torrance County emergency teams. The surviving resident and the affected responders were rushed to the University of New Mexico Hospital in Albuquerque, where medical staff established a secure quarantine area to evaluate, decontaminate, and monitor the patients.
Hospital officials confirmed that while the majority of the exposed responders were assessed and subsequently discharged, three symptomatic patients remained under close observation. Two of the responders were listed in serious condition. Mountainair Mayor Peter Nieto stated that town EMS Chief Josh Lewis, who was the first person to enter the home, was among those held overnight for observation.
State and local authorities are actively investigating the precise cause of the medical emergency. Investigators from the New Mexico State Police and specialized hazmat teams from Albuquerque Fire Rescue are working to identify the chemical composition of the unknown substance.
