UPDATE, September 17: Shrewsbury Police have developed a suspect in this case and are seeking a Jefferson County man for questioning.

Police are looking for a man who stole anhydrous ammonia, a chemical used in the manufacturing of methamphetamine, from a Shrewsbury factory.

The tank of anhydrous ammonia was taken from the storage area of the Carr Lane Manufacturing loading dock at 4200 Carr Lane between 12:30 and 1:30 a.m. September 3, according to the Shrewbury Police crime blotter.

The suspect, who is white, drove a silver or gray four-door truck with a sunroof and four-wheeler ramps in the back. A white woman was in the passenger side of the car.

Anhydrous ammonia is an effective, low-cost nitrogen-based fertilizer used by many farmers, but the chemical is also a vital component in “shake and bake” methamphetamine.
