Four people were taken into custody after raids at two separate cannabis cultivation sites in Tehama County. On Monday district attorney investigators led searches on 68th Avenue in Los Molinos and at Viola and Orchard Avenues in Corning. Between the two locations a total of 6 greenhouses of about 50 by 100 feet were found to contain more than 1,700 growing plants. Two men from Santa Rosa, one man from Tehama and a 17-year-old boy were taken into custody.
