of her school, fall for michelle. how serious were you with her? well i was very serious. it was my first girlfriend. this is the most serious relationship i ve ever had. but it ended when he went to college, michelle had plenty of admirers, she had dated and broken up with a guy named andy. her friends thought this andy had a hard time letting go, which may have prompted this exchange. she was a little bit weekly in class that day, and when i asked her what was happening, what was going on her s response was that she was just tired of by her senior year, michelle was focused on college. she definitely conveyed to me that she was ready to put high school and cedar rapids behind her. kirk thomas, the guy she hung up with before she was murdered, said she was prepared to leaving the building when they said their goodbyes. you don t think that that person is going to walk out the
straw and it immediately goes to the state lab. they told us, hey, he is not your suspect. the next brother was donald. this brother donald, was a father of three and had five grandchildren. he lived in davenport, iowa, and was the manager of a lumber yards before retiring. went denlinger to his house and staked it out surreptitiously. the first time we corrected was out of the trash by the set by the curb. we found a toothbrush in there and collected some dna off of that. and what did the lab think about his genetic material? they said the same thing. he s not your guy? he s not your guy. it came down to the youngest brother, jerry burns, who like brother can t, worked lived and worked in manchester. denlinger did some intel on him. in 1979 he had two young kids. he lived in manchester. he sold farm implements. was in a bowling lead. so, these married with children, 9 to 5 guy? yeah.
rapids police department. but when matt denlinger took over as lead investigator in 2015, he still thought dna would solve the crime. so, he did another deep dive into a case file that had been built by so many before him. now, we re just trying to find men who were listed in these reports, that could have possibly had a connection to her, or men that would ve had a connection to the mall. i thought eventually, if we come enough people, we re gonna get our suspect. that after more than 125 tests, no one matched the killers d. o. t.. they were out of leads. and then parabon comes into this. what is that? parabon is a private lab. what parabon was offering is to take the genetic profile that we had and to create an image. create an image? yeah like an actual a me like an up in the office photo to be on the lookout for this guy? exactly, a computer generated, philly sketch.
