knock down the theory that anthony garcia killed two people in 2008 and two more in 2013 out of revenge. we ve got to get rid of her stupid quote. who? what quote? the shakespeare quote, shall i not revenge or whatever. reporter: according to the defense team, anthony garcia had no motive to kill anyone. what s wrong with the prosecution theory that anthony garcia blamed the people at creighton for everything bad that had happened to him since he left creighton and the idea that when people would check out his resume, they would inevitably get back to creighton and they d get a bad report about him. the problem with the state s theory is that anthony garcia would ve been unaware of those communications. they don t let people in on those communications. reporter: on the other hand, they pointed out, dr. hunter had actually handed garcia this short letter of recommendation after garcia was dismissed from creighton. it got him his next job,
we just kept waiting and waiting. but that question was foremost on everybody s mind. who could have done this? reporter: detectives returned to the theory that either dr. bill hunter or his wife dr. claire hunter might have been the intended victim. between the two of them, they figured, bill hunter s position at creighton made him the more likely target. he basically oversaw all the students that were going through this pathology training program at creighton university. and if there was disciplinary action to take, he would be the individual, among others, you know, to have a direct impact on those students lives. reporter: so, potentially a lot of suspects there. potentially yes. reporter: so, the detective went to the pathology department at creighton and started asking questions. were there any individuals interacting with these folks at the time this occurred that you believe could be responsible for whatever reason? if there is a potential motive, what do you thi
reporter: how many of you were sitting there reading files? there were 21 of us assigned to the tank force, and i think at some juncture almost all of the detectives would get assigned files from creighton. reporter: in those personnel files were several names that looked promising. those who were nowhere near omaha on mother s day were eliminated, but a couple of weeks after the brumback killings, detective mois says, his boss handed him a three-ring binder from 2001. this one was thicker than the rest. and what i took away after reading that file from front to back was that, in my mind, there was enough information contained in that file that it made a very real possibility that there was a motive to want to harm dr. hunter, dr. brumback or dr. bewtra by that individual.
son, tom and his house cleaner shirlee sherman. the latest victims were dr. roger brumback and his wife mary. and at 2:19 p.m., on the day the brumbacks were last known to be alive someone had tried to break into the home of a third creighton pathologist, dr. channda bewtra.
racking my brain. i mean, i we live a peaceful existence, uh, almost ridiculously simple. reporter: dr. william hunter, known as bill to friends and colleagues, ran the pathology residency program at nearby creighton university. his wife, claire, also a doctor at creighton, was in hawaii that day attending a conference. her husband had to break the awful news to her from the police station. how is your wife? crushed? is she going to be okay? she has a work mate that s with her. so she s not alone? no. that s that s that s good. reporter: the hunters had four boys, two grown, one in college and tom. jeff, a student at the university of nebraska in lincoln at the time lived closest. he says it was about 8:00 that night when he happened to check his phone. i had all these missed calls from friends, family.
