A major marijuana growing operation is out of business in Omaha after police raided a home near 120th and Douglas. Inside, officers found more than 400 plants in various stages inside the home. As the officers were dismantling the growing operation, the residents of the house pulled up. The house was located in a cul-de-sac and a police officer blocked the entrance so the suspects could not leave. Police arrested Jason Brasch and Corey May. Neighbors say prior to these people moving in, it was known as a party house but things had calmed down. The only thing they noticed out of the ordinary was that the current residents had visitors at odd hours.
