Killer Thinks He Got Away With It — 40 Years Later, Police Knock

#TrueCrimeDocumentary #coldcases #coldcasesolved For 39 years, Jerry Lynn Burns lived in plain sight as a quiet Iowa businessman, husband, and father of three. No criminal record. No fingerprints left behind. No apparent motive. In December 1979, 18-year-old high school senior Michelle Martinko was ambushed and stabbed 29 times in a mall parking lot in Cedar Rapids, Iowa. For four decades, the case baffled investigators and destroyed families—until modern genetic genealogy and a discarded drinking straw turned the case on its head. In this deep dive, we break down the forensic manhunt, the generational promise made by two detectives, the controversial Pizza Ranch surveillance sting, and the chilling jailhouse confession that exposed a killer who believed he had won.
