New Mexico's attorney general on Friday opened a criminal investigation to determine whether U.S. Drug Enforcement Administration agents broke state law by allowing hundreds of thousands of fentanyl pills to reach the streets of Albuquerque.

The extraordinary inquiry comes less than a week after that DEA agents repeatedly monitored — but did not seize — shipments of the synthetic opioid in a bid to build bigger criminal cases between 2023 and 2025.
