Ming Sen Shiue kidnapped Mary Stauffer and her eight year old daughter Elizabeth outside of a Roseville beauty salon on May 16, 1980. Six year-old Jason Wilkman was also soon kidnapped at Hazelnut Park in Arden Hills for witnessing Shiue stop his car to check on the two. The FBI helped Hennepin and Ramsey Counties search for seven weeks to no avail, until Mary herself called the Ramsey County sheriff on July 7. Strangeness abounded.
The motive for this kidnapping stemmed from back in 1967 when Mary Stauffer had been Ming Sen Shiue's tenth grade algebra teacher at Alexander Ramsey High School. Shiue claimed that Stauffer had given him a grade that he felt was undeserving and believed it caused him to lose a college scholarship. This, in turn, led to him being drafted to Vietnam where he became a prisoner of war (though this did not actually happen).
Mary Stauffer's father testified in the trial that a man had broken into his Duluth home in 1972 and held him at gunpoint before realizing that he had the wrong house. As it turns out, Mary was spending five years in the Philippines as a missionary. Shuie kept searching though, and when he heard that she was back in town, he tried to break into her family's apartment three times before the actual kidnapping.
Shiue kept the Stauffers locked in a closet with a crocheting hook and yarn and some crayons. Eventually, Shiue would bring them out for dinner and to play games like the family he desired. At one point he rented a winnebago and drove them all to Chicago and Madison on vacation. It was during this time when Mary yelled for help from the parked vehicle, and while a group of young boys came over to talk, they did not believe her story.
Back in his apartment, Shiue frequently took pictures and filmed himself raping Mary with the thought that these tapes could be used to embarrass her if she ever got away. These videos include Shiue mentioning that he did not appreciate the bad grade she once gave him, claiming that it ruined his life. However, it was also deemed in court that Shiue had developed an 'abnormal sex drive' and thought Mary was in love with him. Elizabeth even testified that Shiue had put a plastic bag over her head when Mary refused to kiss him.
Mary Stauffer was able to escape her confinement by removing a hinge pin from the closet. The Stauffers were recovered from an apartment in Roseville, though there was no sign of Wilkman. The perpetrator's van was then quickly discovered outside of a stereo shop in St. Paul and Shiue was arrested. He was deemed guilty and not insane on September 17, 1980.
But what of Jason Wilkman? He had originally been stuffed in the vehicle trunk, but the Stauffers said that he was removed soon after. They heard gunshots from afar, but Shiue claimed that he only fired his gun to scare him away. However, Shiue made a deal with law enforcement to reveal the location of where he left Jaon if they did not push for a first degree murder charge.
Jason's body was found on the Carlos Avery game refuge on October 27, 1980 with his skull broken and body covered with branches. Shiue was accused of second degree murder, with an admission of kidnapping but a not guilty plea for murder due to insanity. The trial took place during January and February 1981.
To build a case of insanity, the defense mentioned that Shiue had been traumatized after shooting and killing a burglar at his stereo shop in 1979. He had also received psychological help when he was fourteen years old after he tried to set an apartment building on fire. However, the prosecution believed that Shiue grabbing Jason during the kidnapping was because he knew what he was doing was wrong, thus he was aware of his own actions.
And then: February 8, 1981. Mary Stauffer was on the stand testifying that she did not hate Shiue because the Bible says to love your enemy. It is then that Shiue caught two guards by surprise and rushed to Mary, holding her hostage and slashing her face with a small knife. Officers were able to subdue him and the trial continued, though Mary (requiring sixty two stitches) was excused. The knife turned out to be hidden in Shiue's pants, and while he had been pat searched, he had not gone through a metal detector. The knife had been acquired from two fellow inmates after Shiue found himself in the middle of racially-charged fighting.
Ming Sen Shiue was found guilty on February 21, 1981. His sentence was to serve forty years for Jason Wilkman's death at the same time of a life sentence for the Stauffers' kidnapping, which was criticized for essentially letting him get away with murder. He apologized to the Stauffers in court thirty years later on April 19, 2010 during a trial to determine his freedom. He was denied his appeal.
