Two suburban St. Louis men face federal charges for possessing and intending to distribute enough fentanyl for 1.5 million doses of the dangerous synthetic opioid.
Authorities say three southwest Missouri jailers have been taken to a hospital and a white powdery substance that was found at the jail has tested positive for fentanyl.
Federal prosecutors say a former pharmacy technician at a Springfield hospital stole morphine and fentanyl and then replaced the drugs with saline solution.
