CALLAWAY COUNTY, Mo. — A three-vehicle crash on a Missouri interstate led to a pot bust after a vehicle spilled 500 pounds of marijuana across multiple lanes of traffic — and it happened on none other than 4/20, the unofficial cannabis holiday. 

Missouri state troopers found packages of marijuana scattered on Interstate 70 in Callaway County, about 100 miles west of St. Louis, around 7:15 a.m. Wednesday. 

Police said a pick-up truck lost control and hit the back of a semitrailer as the semi tried to avoid a previous crash. Another semitrailer then swerved to the left side of the road and hit the pick-up. 

Two men, a woman, and mounds of weed were inside the pick-up (before the marijuana inevitably spilled onto the highway). Police said everyone inside the pick-up had moderate injuries, but no one was seriously hurt. 

About five hours after the crash, police arrested 34-year-old David Mora Navarro and 32-year-old Victor Gonzalez Acosta in Montgomery County. Navarro was driving the pick-up, while Acosta was a passenger. 

Both men, who are from Mexico, were charged with felony drug trafficking. Navarro faces an additional charge of careless and imprudent driving, resulting in a crash.

As for the marijuana, the Missouri State Highway Patrol said it took more than one patrol car to transport all of the pot to an evidence room
