An official at the San Juan County sheriff’s office, Megan Mitchell, called the incident “an open and active ongoing investigation.” Mitchell said she did not immediately have more information.
Federal agents from Phoenix were headed to Farmington, the Bureau of Alcohol, Tobacco, Firearms and Explosives said via Twitter.
Farmington is a city of nearly 50,000 residents in northwestern New Mexico, near the Four Corners region. It serves as a modern-day trading post to the adjacent Navajo Nation and is a supply line and bedroom community to the region’s oil and natural gas industry.
In recent years, cafes and breweries have cropped up downtown alongside decades-old businesses that trade in Native American crafts from silver jewellery to wool weavings. Travelling Broadway shows make regular stops at the expansive community centre auditorium, while rural lots on the outskirts are littered with disassembled oilfield equipment.
