MAPLEWOOD, Minn. (AP) - Police are investigating the shooting death of a 41-year-old mother in suburban Maplewood.

Authorities identified her as April Marie Tennin. Police Chief Paul Schnell says investigators considered her husband a "person of interest" in Sunday's slaying. He says there was an argument before the shooting.

Police found his vehicle in a north metro city but think he fled in a different vehicle. The husband was still missing Sunday night.

First responders were called to the home just after 6 a.m. Sunday. Tennin was dead from an apparent gunshot wound. Three children ages 12, 15 and 16 home at the time. Schnell says the children found their mother. He says the husband is not their father.

Schnell says investigators have recovered a weapon.
