people were gonna come across a suspect. it was fascinating how they went about the investigation. we got a call, we ve got three brothers. we think one of them is the color. that they didn t know which one. so, you ve got a live one? we ve got live one here. what do you think at that moment? we re ecstatic. we re ready to go. he was sitting at a booth right by the window. there you are the next ? it s hard to enjoy your food when you think you re staring at that killer. hello and welcome to dateline . teenager michelle martinko was blessed with beauty, brings and compassion. but her promising future was cut short when she was savagely murdered. that dreadful night was ice cold, and after four decades, so was her case. then, a stunning scientific breakthrough helped detectives whittled down a list of suspects to unmask a killer hiding in plain sight. here s dennis murphy with and then there were three . it was an act of unspeakable violence. it w
excuse me i sent a little skeptical. that sounds like food science fiction. [laughs] you re gonna take a molecule of human genetic material and turning into an image of somebody? correct. three sketches were greeted from the dna profile. the suspected killer imagine that is 25, another age 50, and one with a typical 1979 hair cut. police released the pictures to the public. we were hoping that 100 people would call in and say, that looks like person a. the problem is, we got 250 people call in and say it looks like 100 people. oh, man. more needles, more hair stacks. yeah, a lot of rabbit holes we went down. i tracked down another 50 people and swapped them. each time, hoping that this would finally get our guy. but with each dna test result, that hope was dashed. then, in 2018, parabon helped
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. excuse me i sent a little skeptical. that sounds like food science
skeptical. that sounds like food science fiction.
