On Tuesday, March 31, 2026, a Trooper assigned to the Alabama Law Enforcement Agency’s (ALEA) Motor Carrier Safety Unit (MCSU) conducted a commercial motor vehicle (CMV) inspection on a tractor on Interstate 20 near the 143-mile marker in St. Clair County that led to a significant drug seizure.
During the course of the inspection, the driver of the tractor provided an invalid driver license. The driver, who was determined to be an illegal immigrant, was later identified as Dajun Sun, 57, of Oregon City, Oregon. Further investigation of the tractor revealed 23 boxes that contained approximately 185 pounds of marijuana.
Sun was arrested and officially charged with Drug Trafficking and Operating a CMV without a Commercial Driver’s License (CDL). He was booked into the St. Clair County Jail with a
$1,500,000 bond.
