for two long months attorneys for both sides hammered at the question, what happened to nancy cooper? the defense charged the police more than dropped the ball. their investigation was dishonest. the erasing of nancy's blackberry, for one thing, had to be intentional, said the defense. nonsense, applied the prosecution. besides, they claim, they already found what they needed from that phone through other sources. >> we lad her phone records. we knew everything she had done. we had the billing to know how much texting she did or didn't do. we knew her friends. >> the idea the police might have inserted the google map search on brad's computer, they couldn't have, said detective daniels. >> none of the people that work for me or work in the department would have had the knowledge to go in and do something like that.
