Jon,
My thoughts and prayers are with everyone who is impacted by this tragedy. I heard on the evening new last night that an arrest was made last night in Riverside, I hope that this is in fact true and that shit bag pays for what he did. Thank you for sharing those pictures, it must be an honor for you.
I saw that dash cam video and if that is him getting into the truck after the shooting, then I hope he burns in hell and dies a slowy and painful death. That Son of a Bitch calmy hopped into the truck like nothing happend.
