Further Details of Shooting

My mother was on her lunch hour and was down at Lane Bryant, shopping, when she heard the shots.  She says it happened after 12:04pm and only heard about four shots.  The sales associates and shoppers in Lane Bryant went in the back room.  Mom said they were looking for the driver of a van so possibly police are still looking for this driver but are telling CNN they aren't looking so the driver won't know the police are looking for him.
