DNA Helps Cops Arrest Teen’s Alleged Killer in 40-Year-Old Iowa Cold Case

An accused killer appeared in court 39 years to the day after the brutal slaying of a beautiful teenager. Jerry Lynn Burns, 64, who is accused of murder in the first degree, was held on $5 million bail in an Iowa court Wednesday. Police said cutting-edge DNA technology helped them construct the face of the suspect after nearly four decades. In 1979, 18-year-old high school senior Michelle Martinko was stabbed to death inside her car in the parking lot of a shopping mall in Cedar Rapids.
