comments about this phone call the russian authorities are allegedly eaves dropped in between her and her son talking about jihad? >> reporter: this is a phone call with both parents who pretty much are in a stressed out, dramatic state. the father could only tell me he was sick and the phone call ended. the mother elaborated a little more, talking about his high blood pressure. most importantly, his trip to the u.s. is off until his health gets in better condition. no idea when that's going to be. she did say, though, when she's told she can meet dzhokhar, who is currently in custody, she will endure any risk of outstanding shoplifting allegations and the potential of the investigation with the phone taps, could potentially widen further inquiries. she said she will endure that risk just to go to the u.s. but no comment at all on those particular phone conversations, anderson. >> joe, obviously we naturally think this dna could be from tamerlan's wife. it appears from erin's reporting that dna was taken during their meeting with her in the family's home. are officials saying anything
