A 53-year-old woman has been charged with fatally stabbing her fiancé in her western Wisconsin home.

Marian Smith of New Richmond was charged Monday in St. Croix Circuit Court with first-degree intentional homicide and resisting or obstructing police in connection with the death Saturday morning of 48-year-old Shaun Lewis of New Richmond.

Smith remains jailed in lieu of $500,000 bail. She is due back in court Friday. A message was left with her attorney seeking a response to the allegations.

A call from Smith to emergency dispatch shortly after 6 a.m. sent New Richmond police to the home in the 600 block of N. 2nd Street.

Officers and emergency medical personnel found Lewis on the floor "with what appeared to be multiple wounds," a statement from police read. He died at the scene.

The charges say Smith told law enforcement various accounts of what happened, including that Lewis fell on a knife as the two argued and pushed each other.

An autopsy conducted by the Ramsey County Medical Examiner's Office concluded that Lewis died from a stab wound to his abdomen, the charges read. He also suffered a less serious stab wound to his chest.
