and of course, we have a suspect, catherine russell. obviously what happens when there is no match? then where do we go? the fingerprint might be something we can check against a database. it might be extremely important information. we finally have a lead. but there also may be other information we haven't learned about yet. there may be something else's genetic profile on another fragment that hasn't been reported. >> well, it will be fascinating to find out if there's any match at all. of course, there is that potential for all of the dna that was actually at the bombing site itself. more on that. i hope you'll join us as we dig deeper. as the investigators do this kind of work, they're also trying very hard to get inside the heads of the crime suspects. in this particular case, they may literally want to do that, literally. physically examine tamerlan tsarnaev's brain. you know that tamerlan tsarnaev was a boxer. a two-time new england golden glove champion. you play not know boxer and football players and soldiers have cte, repeated blows to the head. one of the foremost expert
