Two men escaped from a McDonald County, Missouri jail Wednesday. John Weeks and Christopher Walker escaped by climbing through an AC duct and a new construction area. Guards believe they removed shower heads to gain access to the duct. The two are believed to be traveling in a silver 2006 Dodge Caravan with Oklahoma plates 073-DLV. Weeks was in jail for assaulting an officer and Walker was there for resisting arrest. Both are considered dangerous.
