how many times did you hear the name michael belenky? i can t give you an accurate answer as how many. but his name came up again and again. reporter: dr. belenky was a former resident who d had left the pathology program and threatened to sue creighton a year before the murders at dr. hunter s home. he had had some trouble during his time at creighton university, but they weren t unlike other people s troubles. but he was just a little bit more boisterous about his i guess his perceived treatment by creighton university and some of the staff there. reporter: dr. belenky told detectives he d been working in pittsburgh on the day of the dundee murders. pittsburgh s like 900 miles from omaha, so correct. reporter: you re not driving that in a day. correct. reporter: presumably you re not doing that without air travel. right. reporter: and air travel s something you can check. right. we knew he was on the schedule. i believe we knew he had logged into his e-mail
meaning things got broke. reporter: kelly says that relationship became so tempestuous, so difficult that shirlee got involved and actively tried to keep the boyfriend away. at one point in time she was thinking about getting a restraining order, mainly for my daughter s sake. she would tell me, he can t come over. and i would sneak him in. one time she come walkin around my house with a hammer in her hand and saying, i want his blood on this hammer. she hated him that bad because of what he had been doing to me. reporter: in spite of that, kelly stuck with the man, got pregnant and had a baby with him. and it got uglier from there. she actually started the process of getting my house out of my name. so that she could keep him out of the house? right. reporter: after shirlee died, what had been a very private and embarassing family feud became fodder for public speculation.
their dna evidence establishes undeniably, unmistakably and without doubt that the murders were committed by two people and not anthony garcia. reporter: the claim was based on what the mottas believed to be a potential match between some unidentified dna found on shirlee sherman s bandana and some dna taken from a suspect in another case. they are taking alleles from dna, bits and pieces, and coming up with a theory that never made it to trial, but she throws it out there on the eve of trial, and prosecutors are incensed, and it really chapped the judge. reporter: the judge took it as a clear attempt to send information to potential jurors that the state s case was suspect. as a result the trial was postponed again, and the judge effectively kicked alison motta off the case.
more pressing was what detectives were hearing from the neighbors. several said they had seen a stranger walking near the hunter home late that afternoon. tell me about the person neighbors described. an olive-complected male who was heavyset dressed in a collared shirt. some describe a jacket, possibly like an ill-fitting suit with a shoulder bag. and several people would correlate that individual to a silver honda crv. they identified the actual make of car? yes. that all seems pretty helpful. very. the same individuals would describe that that vehicle was missing a front plate. but they would describe the rear plate as kind of a white background with dark lettering and kind of describe a multiple-colored sunset or kind of a pastel sunset. so it s not a nebraska plate. out of state is what our feeling was, yes. reporter: based on nieghbors
of the blood that was apparent and where it was located on the walls and so forth. reporter: her arms and hands were covered with defensive wounds, and there was a deep gash on the right side of her neck. beside her lay two kitchen knives. for derek mois and his partner, it was a jolt of electricity and a big hit of deja vu. we were like, this is something here. we have, you know, it would seem a connection. reporter: this is the same guy. this is the same perpetrator, yes. reporter: that s a pretty big moment. it was, very. reporter: just as before, nothing was stolen, and the killer left no fingerprints or bloody footprints behind. but these victims had obviously put up a fight. the additional gun parts found near the front door and the nine millimeter gun clip with nine bullets remaining seemed to be proof of that. what do you make of the gun parts in the doorway?
