The fatal stabbing of a 45-year-old woman in a downtown Minneapolis parking ramp over the weekend was ruled a suicide on Thursday.

The woman, who had no permanent address, died of self-inflicted sharp-force injuries, according to the Hennepin County medical examiner's office.

An employee at the Downtown Auto Park ramp on 9th Street and LaSalle Avenue called security at about 9:30 p.m. Saturday after finding the woman lying on the ramp floor. Police had called the woman's death "suspicious."
