it's not tim hennis.a pubic hair where the rape took place. >> what is male dna doing under mrs. east burn's fingernails? it's not tim's. there's dna under the daughters' finger nail and it's not hennis. >> underneath the fingernails, that's not timothy hennis. but what is that vaginal swab? >> to me male dna under the finger nail of a woman who is raped is pretty damaging evidence. who is it? >> the finger nail scrapings weren't enough for a full dna profile so the defense asked to test all the crime scene evidence that might point to a different perpetrator, including a blood-soaked towel. >> now, whoever had sex with her didn't necessarily kill her, but you can't argue that whoever cleaned up the blood didn't have something to do with it. let's find out what happened. >> in the military, if you need a test done, you have to ask a judge to make the army do it for you. >> the judge, though, denied the defense's request to test other items. >> i can't imagine a judge in a civilian court not allowing that.
