The back of the vehicle was stuffed with several sacks filled with the synthetic opioid fentanyl, as well as 914 pounds of crystal meth, 88 pounds of cocaine and 18.5 pounds of heroin, police said. The driver was arrested.

Fentanyl can be fatal in doses of just a few milligrams. To put the size of the haul in perspective: four and a half pounds of the drug that was seized in Columbus, Ohio last year was said to be enough to potentially kill the entire population of the city of 860,000 people, according to prosecutors at the time.
