A Rapid City woman accused of stabbing a man to death Saturday is held on $100,000 bond. Police arrested 32-year-old Lorraine Swallow for the stabbing death of her nephew, 28-year-old Tyrell Bull Bear. Bull Bear was reportedly stabbed twice during a heated argument. A witness told police that Bull Bear was in Swallow’s face, preventing her from leaving a room. Swallow claims she stabbed Bull Bear in self-defense. The homicide, Rapid City’s third for the year, was in a home on Castle Heights Place, off of Sheridan Lake road.
