Duane Johnson told deputies that his wife had been a patient in a nursing home but begged him to take her home to die. Officials at the New Ulm Medical Center told investigators Debra Johnson had been at a nursing facility following two heart attacks.
She also had diabetes and high blood pressure, as well as mental illnesses for which she took antipsychotic medication, the Free Press reported.
Duane Johnson took his wife home against medical advice, the newspaper said.
In her final days, Duane Johnson said, she had stopped taking her medication as they used meth and "rocked out" to their favorite band, Quiet Riot. The court documents allege when Debra Johnson couldn't eat or drink, her husband used snow to moisten her mouth.
Duane Johnson said his wife suffered convulsions during that time frame, but would not allow him to call for help, the Free Press reported. He told investigators he held her to keep her from hurting herself during the seizures.
Johnson also told investigators he and his wife had sex about two hours before she died, the newspaper said. After her death, he washed her and wrapped her in linen "like the Bible told (him) to do," the court records said.
Detectives found several guns, including four rifles and two shotguns, in the home, as well as hundreds of rounds of ammunition. Duane Johnson told them he had 47 guns, several of which were stolen.
