"They were already potted," Police Chief Tim Clothier told The Kansas City Star. "They were well-maintained by whoever owns them."
The police have also made a post on their Facebook page encouraging the owner to "please contact the Ozark Police Department to make arrangements to have the plants returned." Though, we wouldn't recommend doing so, as growing and possessing cannabis in Missouri is still illegal. In fact, you can face 3 - 10 years in prison and a $10,000 fine if you get caught growing more than 35 grams of marijuana in Missouri.
When asked what he thought the motivation was for leaving these plants out in public was, Clothier said he wasn't sure.
"I don’t know," he said. "There’s a thought among some criminals, if you’re going to break the law, do it right out in the public. Nobody will ever notice."
The police department says the will keep the plants for 30 days in an evidence locker before having them destroyed.
