people, if you know nanything e please come forward. dave? >> it's a strange thing to say when there is nothing to suggest he needed help to do this. he had nothing but time. all he did was gamble, clearly had a lot of cash. that's certainly raise the questions. >>reporter: you're right. and so, dave, then you have to ask the girlfriend, because she was retired too, was she ever in the car? she was in the homes. she was in so many areas where that ammunition was, along with all the weapons. what does she really know? >> she remains the most important person in this investigation. thanks so much. of course with all the talk about motive, we can't forget the victims. 50 of the 58 victims who lost their lyes have been identified, 10 more names added to the list on yesterday.
