According to the Blue Earth County sheriff, Mercede Johnson lives with her boyfriend in his mom's place on the outskirts of Mankato.
Around 6 a.m. last Saturday, Johnson's boyfriend, identified as "SW" in court documents, walked up to his mom's bedroom and told her, "Mom, she stabbed me in the ass."
Johnson followed him, telling the mom her son just fell on the knife, and then the two started fighting. Typical early morning bliss from two swooning lovers.
About a half hour later, the Blue Earth County sheriff received a few phone calls. The first reported the butt shanking and that SW was now driving through neighbors' yards in his mom's red Pontiac. The second was from Johnson, telling police her boyfriend was drunk, bleeding, and tried to run her over in his mother's car.
Deputies eventually tracked down SW at a neighbor's house and found him just as advertised.
SW had scratches on his face and neck, and told police he got "shanked" in the ass. The deputy he was speaking to had him drop trou and sure enough, he observed a puncture wound about a half-inch in diameter on his butt.
The neighbor told police he came over at about 5:40 a.m. with scratches on his face and said he didn't want to go home because he was afraid of Johnson. He went back anyway, and returned a short while later yelling, "Hey, hey I've been stabbed."
Both Johnson and her boyfriend were obviously drunk to the deputies; SW admitted they had been drinking at Oleander's Saloon earlier that night. SW tried to change his story and say he didn't really know what happened and he could've been accidentally stabbed while they were play wrestling, but eventually officers got him to confess that the shanking was intentional.
SW claimed his girlfriend did it because "when Johnson drinks, she gets crazy."
Johnson stuck to her wrestling alibi and kept telling officers her boyfriend was "nuts."
A detective got a search warrant and searched the mom's house, but they were unable to find a knife with blood on it. Johnson has been charged with felony 2nd-degree assault with a dangerous weapon and misdemeanor domestic assault. The charges carry a maximum of $15,000 in fines and just over seven years in prison.
Johnson has at least seven alcohol-related misdemeanors on her record and one prior domestic assault charge, although that was dismissed.
