Guests at a local motel were evacuated overnight after a suspected meth lab was discovered during a police response to a domestic disturbance. Sunset Hills police were called to a room at the Econo Lodge Inn at Lindbergh and Watson Rds. around midnight. While investigating that incident, an officer discovered another crime in progress in a different room. Sunset Hills police chief William LeGrand says the officer saw a subject sitting outside the hotel cutting batteries with a pipe cutter. The policeman then saw smoke and pushed the room door open to make sure that there wasn't a fire. At that point, the Chief says, the officer was overcome a bit by the fumes. The subject was arrested. He had apparently been attempting to cook methamphetamine in the room. After St. Louis County police Hazmet crews inspected the area, guests were allowed to return to their rooms. The officer was taken to the hospital, treated and released. Charges have not yet been filed.
