back with our panel now, former mayor of new york, rudy giuliani, fran townsend, jeff toobin, jeffrey beatty, juliette kyyam, and with us, jeffrey vasquez, knew the older suspect and coached the younger suspect when he was in high school. luis, i appreciate you joining us very much. you saw them both the last time about two years ago. >> two years. ? first of all, tamerlan, you knew him more than the younger suspect, right? >> that is correct. he and i were friend, just in the hallway. the way we got to know each other was my wife -- sweetheart, high school girlfriend. she was friends with the sister, her name was bella. so him being a protective big brother, that's how i got to know him. and ever since then we keind of would have lunch here and there, see each other after high school here and there. two years ago he just kind of disappeared. i wouldn't see him around anymore. what kills my curiosity, i'm sure a lot of people also, is that what happened in the past
