A weekend investigation of a retail theft turned into something else altogether in Madison.  An off-duty detective determined the suspected thief was a victim of human trafficking.  Madison police spent the rest of the weekend looking for that person’s abuser and trafficker.  No names were released and the trafficking victim was taken to a relative’s home for safe-keeping.  Police say they are trying to track down the trafficking suspect and arrange for an interventionist to help the victim originally targeted for shoplifting at West Towne Mall.
