In May, officials with the Cedar Rapids Police Department held a press conference to discuss a new piece of technology they have utilized in an effort to solve a 37 year old cold case.

Michelle Martinko was killed in 1979. Her body was found in the family's Buick outside the Westdale Mall in Cedar Rapids. The killer has yet to be identified.

The technology used by police took DNA collected at the crime scene to develop a composite of what Martinko's murderer may have looked like.

Since they released the image at the press conference officials with the police department tell TV9 they have received around 70 tips.

"The investigators are in the process of going through each of them," said Greg Buelow, public safety communications coordinator. "It is probably too early to categorize the likelihood of finding the murderer, but investigators have always remained hopeful since the DNA is on file."

Anyone with information about this case is being asked to get in touch with the Cedar Rapids Police Department at 319-286-5442.
