Publish date:

The man who called Blaine police informing them that he killed his wife has been charged with second-degree intentional murder. 

A criminal complaint details the the night of the killing and notes that 46-year-old Matthew Lynn Jansen, of Blaine, admitted to shooting his wife dead during the late evening hours of Friday, Feb. 8. 

It comes after she had served him with divorce papers at Thanksgiving, and had planned to move out of the home they shared on Saturday, Feb. 9.

Blaine PD officers were sent to their home on 95th Ave. NE after Jansen called 911 saying he shot and killed his wife.

Police arrived and directed Jansen to come outside, which he did without incident. 

Once inside the home, officers found 46-year-old Mary Jo Jansen dead on the floor in an upstairs bedroom. The Anoka County Medical Examiner determined that she died from gunshot wounds to the neck and chest. 

On the steps inside the home was a 44-caliber Smith & Wesson handgun, which was traced back to an empty handgun case in a truck parked inside the garage. Police also found a receipt from a local Fleet Farm that showed gun was bought earlier this month. 

Jansen was quoted by officers as saying: "I can't believe I did it" and "I guess I don't have to worry about a divorce now."

Investigators learned that they had remained living in the home together while the divorce was processing.

Family members also told investigators that the Jansens removed all guns from their home following an incident in December, although the details of the incident aren't clear. 

Second-degree intentional murder carries a sentence of 30-40 years in prison if convicted.
