stolen 2016 GT Bicycles Aggressor

Went grocery shopping at walmart on the way outside seeing one of my other bikes inside of the building came outside to an employee who did not know that my other bike was just rowed off by the perpetrator they told him to leave apparently I'm not sure why the Walmart stock did not use their p. A. System to notify us of our bikes being stolen or almost stolen if they thought only one was mine. I had another lock on it as well. Which Was a lock with motion sensors And a 110db sound alarm .battery was removed lock was cut .
