>> let's be practice couple -- practical about this, there are two adults in this house and two dead children. and darlie is sliced and cut and beat severely. well, the most logical culprit of that, if it is not an intruder, would be the husband or darren. >> in addition to defending darlie, doug mulder had represented darren in his gag order case. >> well, we alleged in several appellate pleadings that mr. mulder was suffering from a conflict of interest. at the time that doug mulder represented darlie, he had a continuing duty to protect darren. >> i was in the room when mulder and darren had that conversation. darren had said, you know, well, i don't want them going after me because i didn't do anything. and mulder said, well, you didn't do anything, i don't see any reason to go after you. and that was that. >> it would be very difficult to point a finger at darren when the person on trial said my husband is not involved.
