EAGLE POINT, Ore. (AP) — Law enforcement officials say more than 12,000 marijuana plants in 32 greenhouses were seized from a marijuana grow site in southern Oregon.

The Jackson County Sheriff’s Office says a search warrant was served at a rural property in Eagle Point on Thursday morning. Officials say the property contained the cannabis plants and 3,000 pounds of processed marijuana.

Seven workers at the site were detained, interviewed, and released.

Sheriff’s officials say the grow site had been under investigation for a month and there was no licensing for any type of cannabis growing, handling, or processing.

The sheriff’s office says a primary suspect has been identified.
