officials. a .45 caliber semiautomatic pistol. the firearm was empty, saving the last one for himself. tells me he was counting shots as he was killing victims. >> six shooter. saved a round for himself. >> that's right. obviously what we don't know, still questions i have. i want to know were these victims chosen randomly or did he show up on that day trying to target someone? last that stands out is a whole body of scholarship on this. looks at motivation of the shooters and how they look to anniversaries. in particular dates. learning today that today was the subject's birthday. we may not know unless he had a manifesto of some sort or recovers and is able to talk to law enforcement officers what role that played, but it's chilling. >> awful. and what did you hear in that press conference other than what josh just talked about that you think is important for viewers to hear and to understand?
