MINNEAPOLIS, Minn. - A man sits in jail in Kansas after being charged in a 1980 murder case in Minnesota.
Officers arrested Robert W. Skogstad, 57, on charges of second-degree murder in the killing of a 22-year-old woman in her Minneapolis apartment.
Catherine Steinhardt was found by her sister after Catherine missed two days of work, according to a Minneapolis Police Department news release.
She suffered sharp force injuries, was sexually assaulted and strangled, according to the release.
A pair of Minneapolis homicide detectives went back over the case in 2008 and were able to use DNA technology not available in 1980.
It took two years, but advancements in DNA collection and profiling led to a match for a sex criminal in California.
The two Minnesota detectives came to Edgerton, Kan., in 2011 to talk to Skogstad and get another DNA sample.
He had worked as a caretaker in Steinhardt's apartment building at the time of the killing, according to the police department news release.
Skogstad told the detectives he didn't know Steinhardt and had never had sex with her.
About a year later, enough evidence had been collected to charge Skogstad with the murder.
