The Anoka County sheriff's department is hoping new DNA evidence will help crack a cold case that's nearly 25 years old.
Armonjean Mason was killed was found along a road in Columbus on Dec. 2, 1987. The 40-year-old mother of two was strangled. Officials said her stab wounds didn't appear to have been fatal, and there was evidence her hands and feet had been bound.
Authorities said Monday that DNA tests point to a "person of interest."
Cmdr. Paul Sommer told reporters the test results aren't enough to arrest the person or to call him a suspect. He says investigators tried to talk to him last month, but he declined to discuss the case.
Sommer hopes the new evidence will help bring forward people who have information about the case.
