A Mexican national living in Kansas City, Kan., has been sentenced to seven years and three months in federal prison for growing thousands of marijuana plants in northwestern Missouri.

U.S. Attorney Beth Phillips says 25-year-old Serafin Rodriguez Gonzalez was sentenced Thursday for conspiracy to grow marijuana. He pleaded guilty June 2.

More than 80 officers from 14 agencies raided two growing sites in in Buchanan and Clinton counties in July 2010, and found a combined 7,000 plants. Prosecutors say each location had a campsite with two tents and a tarp-covered living area.

A 45-year-old co-defendant, Juan Francisco Garcia Palomares, also a citizen of Mexico, pleaded guilty to the same charge and will be sentenced Feb. 2.
