“They were telling people to get out of the house,” said Rene Rushon, who lives nearby, “It was really trippy, because nothing ever happens here.”

In all, officers served search warrants at nine homes and removed almost 1,000 pot plants.

One suspected grow house was across the street from Ceres High School. That’s where the officers found pot plants and a neglected horse.

Officers also arrested two men for gun charges. The number facing marijuana charges is unclear.

Officers say vigilant neighbors are the ones who tipped them off. Detectives then compiled a list before hitting the houses all at once.
