Christopher Gallegos, 19, of Temecula, pleaded guilty Monday to conspiring to cultivate marijuana on land in Kern County.

Gallegos acknowledged that he, his brother Salvador Gallegos Jr., 22, Rufino Orozco Martinez, 32, and Jorge Torres, 28, conspired to cultivate 920 marijuana plants on private ranch land. Law enforcement also seized three pounds of processed marijuana and a gun from the grow site. Gallegos is scheduled for sentencing March 8.

His brother and Orozco previously entered guilty pleas and are scheduled for sentencing in April. Torres has entered a not guilty plea.

The Gallegos brothers and Orozco face five to 40 years in prison and a $5 million fine.
