HUTCHINSON— Three of four charged in association with a robbery at knifepoint outside Walmart in Hutchinson have now entered pleas in the case.

Stephen Howard, 18, was the third when he entered a guilty plea Monday to conspiracy to commit aggravated robbery.

The state then dropped a more serious charge of aggravated robbery against him.

Police say on August 3, Howard and three others suspects were drinking and smoking marijuana and decided they needed more cash for cigarettes.

They allegedly went to Walmart and tried to break into vehicles, but then spotted a group of teens on the side of the store.

Two of the suspects wrapped their shirts around their heads, pulled a knife and robbed the four teens of $85.

Howard will be sentenced on Dec. 2.
