an orange yellow health book. he opened up the book and inside were these two lists. i thought at the time we were extremely fortunate that chi mak tore up a note that if we were to stop and think about it, he would have burned or shredded or disposed in a way that we couldn't have found. very little was ever in his trash. bills, that sort of thing. to find that tasking list one time, that was one of the big mistakes he made. when i found those two lists, and i knew we had a tasking list and set of instructions, that validated the whole investigation up to that point. i knew nobody would question our investigation, that we were on the right track. and i knew going forward, that would mean we'd continue to get resources to take it to its logical conclusion. >> vo: so when my windshield broke... i found the experts at safelite autoglass. they have exclusive technology and service i can trust.
