Instead of being a good Samaritan and turning over the bag to store management, they stole it.  A woman who lives in Ferguson was shopping at Walmart over the weekend when she accidently left her pocketbook in the shopping cart and left the area.  She returned a short time later but the pocketbook was gone.  Surveillance video showed an unknown white female walks over, gets the purse, and puts it in the trunk of her car.  The victim's cell phone was being tracked to determine the location of the thief.  Police do have pictures of the thief and her vehicle and are working to identify the woman.  The victim was advised to cancel all credit and bank cards and her cell phone service.  Stolen property is valued at $800. Charges are pending.
