MINOT, N.D. (AP) - DNA evidence might be key to solving the mysterious killing of a Minot State University student seven years ago.
Anita Knutson was found stabbed to death in her apartment on June 4, 2007. Investigators were unable to solve the crime and it now is officially classified as a cold case.
But authorities did recover some DNA evidence. Police Lt. Jason Sundbakken says that if the killer should ever get arrested for another crime and have his or her DNA put into a national database, that could be the break investigators need.
Sundbakken also says that with many cold cases, '"it is just a matter of getting lucky with a tip.''
