METHUEN, Mass. (CBS/AP) Rocky Morrison thought he'd seen everything in his six years of pulling trash from the rivers of northeast Massachusetts.
That was until Sunday, when he grabbed a plastic bag of marijuana floating in the Shawsheen River in Lawrence.
Morrison, of Salem, N.H., helps run the nonprofit Clean River Project. He and his co-workers alerted police.
Lawrence police Chief John Romero tells The Eagle-Tribune that some of the pot had been packaged for street sale, and some was still in plant form.
He estimated it weighed two pounds and had a street value of $2,000.
