Charges: Duluth woman assaulted mother with hammer

Officers found the victim with serious injuries while conducting a welfare check at her Esko residence on Thursday afternoon.


A Duluth woman faces two felony assault charges after allegedly attacking her 60-year-old mother with a hammer.

Amber Rae Stonemark, 35, was detained by police in Minneapolis on Thursday and told them that she had harmed her mother the prior evening, according to a criminal complaint.

The Carlton County Sheriff's Office and Minnesota State Patrol were summoned to conduct a welfare check at the victim's residence on Stark Road in Esko around 1 p.m. Thursday. Officers were unable to make contact with anyone, finding the shades drawn and a mattress propped up against the door, according to the complaint.

Officers breached the door and saw a "large amount of blood in the bedroom and bathroom" before finding the "seriously injured" woman. A hammer also was located in the vicinity, the complaint said.

The 60-year-old told police she had fallen, according to the charging document. But police were unable to take a formal statement due to the severity of her injuries, which were not specified.

The victim was airlifted to St. Luke's hospital in Duluth, where she remained on Monday. There was no immediate update on her condition.

The Minnesota Bureau of Criminal Apprehension was summoned to process evidence at the scene, while police in the Twin Cities took a formal statement from Stonemark in which she admitted to assaulting her mother with the hammer, the complaint said.

Stonemark is charged with first-degree assault resulting in great bodily harm and second-degree assault with a dangerous weapon. Judge Rebekka Stumme set her bail at $200,000 and issued a domestic abuse no-contact order.

Stonemark has prior convictions including first-degree burglary and obstructing the legal process, according to a search of court records.
