DNA Technology Solves Decades-Old Murder Case, A Shocking True Crime Story




Early on December 20, 1979, Cedar Rapids, Iowa police discovered Michelle Martinko's bloody body in her parents' Buick.

Michelle, a blonde 18-year-old, drove to Westdale Mall in Cedar Rapids to do some Christmas shopping. She picked up a winter coat from one of the stores, talked to some friends, and walked back to her parents' car in the mall's parking lot.

Michelle wasn't seen again until four a.m. the next day, two hours after her mother and father reported her missing. Her body, stuffed into the passenger seat footwell, was covered with blood. She'd been stabbed more than ten times in the face and chest.

Her hands were cut up too, showing police that Michelle tried to defend herself.



Hundreds of people were interviewed by the police. Sixty suspects were interviewed. Ten-thousand-dollars was offered as a reward. Police had a sketch of a white man in his late teens or early twenties. But nothing helped police find the murderer.

Tragically, Michelle's parents died in the 1990s. They would never know that police eventually captured a man they believe took Michelle's life.

Twenty-first century DNA technology made the difference. Investigators lifted a man's partial DNA profile from a bloodstain on the car's gear shift and another bloodstain on Michelle's dress.

Using the resources of GEDmatch, a commercial genetic genealogy site, investigators were able to narrow their suspect list to three brothers, all in Iowa. Two were eliminated. That left Jerry Lynn Burns.



Police started tracking his every movement. An officer grabbed a straw that Jerry had used to drink a soft drink. It was sent to the state crime lab, and the DNA on the straw turned out to be a positive match.

Jerry Lynn Burns, 66, was arrested at his office, December 19, 2018, and charged with first-degree murder. The day he was put in handcuffs was also the 39th anniversary of Michelle's death.

Jerry went to trial in August 2020, was convicted, and sent to prison for the rest of his life.

Michelle's older sister Janelle said she only wished her parents had lived long enough to see Jerry marched out of the courtroom in handcuffs.

"We don't exactly know the whys and some of the details," Janelle said, "but we definitely know who did it, and that was terribly important to us."
