On 1/12/18, at approximately 7:34 p.m., four subjects approached a jewelry store. The first subject held the front door open and allowed the other three subjects to gain entry. The first subject placed a mallet on the floor to prop open the door. He then remained in the vestibule and held the outer door open. As this occurred, the other three subjects used rubber mallets and smashed the store’s front showcases. After removing merchandise the three subjects fled through the front entrance and ran in different directions. The subjects were described as four males wearing hoodies.
