PIERRE, S.D. — The South Dakota Supreme Court has upheld the conviction of man found guilty of murder, rape and burglary.

Attorney General Marty Jackley said Thursday the high court rejected all of Dean Kryger’s claims, finding the defendant’s admission that he had a criminal mind was admissible and that evidence was sufficient.

Kryger was convicted by a Minnehaha County jury in February 2016 and was sentenced to life in prison for first-degree murder, second-degree rape and first-degree burglary.

Fifty-six-year-old Kari Anne Kirkegaard was found strangled in her Sioux Falls home in 2014.
