Willie Nelson and tour manager David Anderson will not serve any jail time after pleading guilty Tuesday (April 24) to possession of marijuana in Louisiana. It was Nelson's first-ever drug conviction, authorities said. A judge in St. Martinville, La., sentenced Nelson and Anderson to six months of probation and ordered them to pay $1,024 each in fines and fees as part of their plea bargain on the misdemeanor charges. Nelson and Anderson were arrested along with Nelson's sister and band member Bobbie Nelson and two bus drivers when their tour bus was stopped by a state trooper on Interstate 10 near Breaux Bridge, La., on Sept. 18, 2006. The arrests took place while they were returning to Texas after performing a show with Ray Price in Montgomery, Ala. Police confiscated 1.5 pounds of marijuana and 0.2 pound of hallucinogenic mushrooms, but prosecutor Chester Cedars said Tuesday that all evidence indicated the marijuana was for personal use. "Without a doubt, this is not a case of distribution," he said. As part of the plea agreement, all charges were dismissed against Bobbie Nelson and the bus drivers. Following sentencing, Nelson greeted fans and signed autographs outside the courthouse in the town with a population of approximately 7,000.
