Julio Cesar Villanueva Cornejo, 33, of Michoacán, Mexico was sentenced Monday to six years in prison for possessing a gun and distributing illegal rat poison and insecticides in connection with a large marijuana grow in the Lilly Canyon area of the Sequoia National Forest.

He is subject to deportation after he serves his prison sentence, according to a news release from the office of U.S. Attorney Benjamin B. Wagner.

Cornejo pleaded guilty in December. According to court documents, Villanueva delivered chemicals and supplies to the grow. Native oak trees and other vegetation were killed or cut down to make room for the 9,746 marijuana plants planted there, the news release said.
