BLAINE, Minn. (WCCO) — A man who called police to report shooting and killing his wife has formally been charged with second-degree murder.

Jansen told police his wife had recently requested a divorce, and was planning to permanently move out of their home the day of the shooting. While on scene, police say Jansen said “I can’t believe I did it” and “I guess I don’t have to worry about a divorce now.”
