After finding 100 pounds of pot in a minivan Saturday, authorities in Sweetwater County have now seized more than $4 million in marijuana since October.

The Sweetwater County Sheriff's Office says its canine unit has seized nearly 800 pounds of the drug in less than two months.

The latest bust happened Saturday when a sheriff's office K9 team stopped a 2017 Chrysler Pacifica minivan on Interstate 80. The van was traveling 90 mph in a 75 mph zone, authorities said.

The team found five large duffel bags containing a combined 107 pounds of marijuana in vacuum-sealed bags, the sheriff's office reported. Authorities arrested the driver, Nicholas Wyatt Haws, 24, of Rocklin, California, and his passenger, 22-year-old Rayna M. Quiocho, 22, of Citrus Heights, California.

Both were booked on suspicion of unlawful manufacture or delivery of a controlled substance. They will remain in custody pending an initial appearance in court.

The sheriff's office did not identify the dog handlers or K9s, citing threats in other parts of the country against officers and their dogs.
