life in prison for nancy kissel. r mother spoke to nbc news. >> i think for the moment, she is probably somewhat relieved that this ordeal is over. >> nancy's lawyers have told "dateline" that instead of appealing her conviction, she decided to petition for a transfer to a u.s. prison to serve out her sentence. >> the fact that she has been found guilty of murder doesn't amount to a complete story. we'll never know the truth of this case. it just won't be known. >> even if we did, it certainly wouldn't satisfy the bigger question here, the one about robert and andrew. how is it that two brothers so different in so many important ways could both end up discovered in basements in such grisly fashion. >> the childhood friend from new jersey doesn't know. >> one broke, quite a successful guy. one guy that wants to have the house and the yachts and all that and run a ponzi scheme to keep it going. >> the sad thing is he didn't have to do it that way. he was a great salesman. he could have done it on a legitimate basis. may
