A 43-year-old man was sentenced to more than 30 years in prison Friday for stabbing to death a fellow resident at a state-operated mental health group home in West St. Paul.

John C. Adams II was found guilty in September in Dakota County District Court of intentional second-degree murder in the death of David Rahn, 68, in 2020. Adams will get credit for 1,777 days already served on his 367-month sentence, and was ordered to pay $2,088 in restitution.

According to the criminal complaint, Adams stabbed Rahn dozens of times in the early morning of Feb. 17, 2020, at the home in the 1500 block of Christensen Avenue. After a staff member heard Rahn scream for help and called 911, police found Rahn unresponsive on the floor of his bedroom with stab wounds to his face, neck and back. He was pronounced dead at the scene, and his death was ruled a homicide.

Adams at first claimed self-defense and later said Rahn had stabbed himself. But the medical examiner found evidence that the victim had tried to fend off the attack. Police found a bloody kitchen knife and a pair of blood-soaked gloves inside bags left at a Kingdom Hall of Jehovah’s Witnesses across the street.

Adams was convicted of third-degree assault in 2001 in Hennepin County for smashing a glass in a woman’s face in downtown Minneapolis. The court found him to be “a clear danger to the safety of others” and mentally incompetent to stand trial. His sentence was set aside in exchange for him being put under Security Hospital supervision for at least three years.

In October 2018, Adams was granted provisional discharge from the Security Hospital to the home on Christensen Avenue, but that discharge was revoked less than nine months later for violations of the discharge conditions.

The home of one of three group home operated by the state Department of Human Services for people civilly committed for a mental illness and then discharged from a DHS treatment facility.
