Meet the man who was on a mission to solve the Michelle Martinko murder: Cedar Rapids Investigator Matthew Denlinger ‘indispensable’ in cold case

CEDAR RAPIDS — He didn’t start out thinking he was going to solve a cold case murder that haunted Cedar Rapids for 38 years, but he always believed it would happen someday because the victim’s family deserved to know.

Matthew Denlinger was only 5 when Michelle Martinko, an 18-year-old high school senior, was attacked and stabbed to death Dec. 19, 1979, at the recently opened Westdale Mall. Her body was found the next day in her family’s Buick near J.C. Penney.

As he got older, he learned more about the case because his father, Harvey Denlinger, was a Cedar Rapids police detective at the time. The older Denlinger joined the department in 1970 and by 1979 had been promoted to a detective, now called investigator.

Denlinger, who read through every report in Michelle Martinko’s file — about 7,800 pages — realized authorities needed a new plan to narrow down possible suspects. That new plan emerged after Denlinger bought his wife a gift, but it wasn’t without hurdles to overcome.

A jury on Monday, Feb. 24, found Jerry Lynn Burns guilty of premeditated first-degree murder, a case that Cedar Rapids Police Chief Wayne Jerman said has “haunted our community for decades,” the Des Moines Register reported Feb. 24.

“We don’t exactly know the whys and some of the details, but we definitely know who did it, and that was terribly important to us,” Janelle Stonebraker, Michelle Martinko’s older sister, said after the verdict was read. “I wish my parents could be here to see this.”

Martinko’s father, Albert Martinko, died in 1995. His wife, Janet, passed away in 1998.
 

Full coverage of Michelle Martinko’s slaying, DNA evidence and the 2020 murder trial available at The Des Moines Register and The Cedar Rapids Gazette.

The seven women and five men on the Scott County jury reached the guilty verdict in less than three hours.
