"lost." >> i haven't the slightest idea of where it went. >> wallace did a little research on the hollow-tip bullets bradford admitted he once had. remember, those were the same kind of bullets that killed joan. and wallace discovered that particular type of hollow point is rare. less than one percent of all the ammo sold. >> wow, what are the odds? he's either the unluckiest person in the world, who just happens to have all of these causal factors that happen to align perfectly, to make this perfectly innocent person look really guilty. or he's really guilty. >> so with all those circumstantial clues and a clear motive and means, lewin and wallace drove out to the desert and arrested bill bradford. it was may 2001. 13 years after joan was murdered. >> he had just popped open a beer. i don't think that bill realizes that you will never see this ever again. this is a guy we're just going to vacuum suck out of his life
