I read quite a few news reports and only one said anything about the Walmart shopper exchanging fire with the suspects before getting killed. I did see one who interviewed a witness at the Walmart who saw the shopper get killed but the witness did not say anything about fighting back just that the suspects yelled at everyone to get out of the store. Sadly, if that shopper did fight back, it does not appear to have accomplished anything and I hope that is not what got them killed. The suspects did engage officers entering the rear of the store before killing themselves. Oh, and they managed to drape a Gaston Flag over one of the officers killed at the CiCi Pizza...Nice.
