(AP) — A 52-year-old Colorado man who said he was hauling medical marijuana when he was pulled over in Nebraska has been fined $4,000.

David LaRochelle pleaded guilty on Monday and was fined for possessing more than a pound of marijuana. Prosecutors had lowered the charge and dropped another in return for LaRochelle’s plea.

LaRochelle was arrested July 25 after a Nebraska state trooper pulled him over for speeding. Nearly 7 pounds of pot was found in his vehicle.

LaRochelle, of Crestone, Colo., said in court Monday that he and a friend had opened a legal medical marijuana business in Colorado. LaRochelle said he was taking the marijuana found in his vehicle to another friend, in Omaha, who wanted some to help treat his cancer.
