(KMZA)--A Marshall County man convicted of operating a marijuana grow operation at his residence south of Blue Rapids has been sentenced to more than 4 years in prison.

Gregory Tyner was recently sentenced in Marshall County District Court on five felony counts—including unlawful cultivation of marijuana.

A jury found Tyner guilty on the charges in February.

He was found not guilty on a firearm-related charge.

The Marshall County Sheriff’s Department raided his residence in October 2015, seizing up to 50 marijuana plants and equipment to grow plants.
