Law enforcement officers in Albany County on Friday stopped a vehicle with nearly 40 pounds of methamphetamine, heroin and fentanyl, according to a news release from the Wyoming U.S. Attorney's Office.

Officers were conducting drug interdiction, and identified a vehicle they suspected contained controlled substances, according to the news release.

They executed a search warrant on the vehicle that resulted in finding and seizing about 35 pounds of suspected methamphetamine, one kilogram (about 2.2 pounds) of suspected heroin, and one kilogram of suspected fentanyl -- a powerful anesthetic.

"This case remains under investigation," according to the news release.

The news release did not identify the law enforcement agencies working on the case, where the interdiction occurred, where the vehicle was from or where it was going, the identity of any suspect or suspects, nor whether charges have been filed.

U.S. Attorney's Office spokesman Mark Trimble said in an email that he could not comment further on the case.

The U.S. Drug Enforcement Administration says fentanyl is a synthetic opioid 30-50 times more potent than heroin and 50-100 times more potent than morphine most often used with patients who are already taking other opioids to relieve chronic pain or breakthrough pain caused by cancer. It creates a powerful euphoric feeling with confusion and sedation. Repeated use can cause addiction, respiratory depression and arrest, unconsciousness, coma, and death. As little as two milligrams can cause death.
