on december 29, 1988, richard gladstone reported on the beginning of a meticulous investigation. >>>ld outside of locker why they started pieces. chunks of the nose comb and the cob turned around not enough for a call. the second investigation moved into the second week little changed by the option that said they are a dog. but the news that fragments of a pal lot has given new focus for the hunt for clues. search teams have been combing grounds already well gone over. in hopes of finding something that could tell the experts what kind of baggage held the bomb. where it was carry where it was checked in. then part-time who mate the explosives. recushioners have gathered. >> you're trying to figure out who helped him out. trips to the place where the cockpit landed. to lay flowers then visit the little country church only 100 yards away. >> i don't know if it's a good idea to come here but i think the feel that they're receiving more information here if they stayed in hotels in london. i just don't tell them things i want to hear i tell them some things they don't like to hear perhaps
