A southeast Iowa man was sentenced to 20 years in federal prison this week after a drug bust two years ago. Twenty-four-year-old Jeremy Yocum pleaded guilty to conspiracy to manufacture at least 500 grams of methamphetamine. The charges stemmed from an incident in Keokuk on January 5, 2008.

Authorities were called to a residence in relation to a problem with Yocum. Officers detected an odor of anhydrous ammonia coming from a vehicle belonging to Yocum, who had fled the scene. Officers then found a meth making operation in an outbuilding on the property. At the same time, Yocum returned to the scene and was on top of the roof of the house with a knife in his hand and yelling threats.

After two hours on the roof, officers were able to talk Yocum down and take him into custody. Following the 20 year prison sentence, Yocum is ordered to serve 10 years of supervised release.
