A Duluth man is charged with second-degree murder after authorities say he fatally stabbed his wife during an argument Sunday night after she told him she wanted a divorce. Investigators say 40-year-old Ryan Jazdzewski (jaz-DEW-skee) told them he got into a “horrible fight” with his 41-year-old wife Nicole at their Chester Park home, took a knife she grabbed for self-defense and stabbed her 10 to 12 times. Responding officers found the couple’s seven-year-old daughter with blood all over her clothing, arms and legs. The other children were removed from the residence. Jazdzewski’s arraignment is set for tomorrow (Wed).
