Police responded to the couple’s home in the 1300 block of Bluff Border Road around 1:45 p.m. Sunday after a 911 caller requested a welfare check on 68-year-old Mary Laakso.

According to the criminal complaint, authorities discovered the victims—Elizabeth Kolba, 33, and two juvenile females ages 12 and 13—inside a residence on the city’s west side after responding to a welfare check.

Wisconsin authorities say three people—including two juveniles—were found dead inside a home Monday morning in New Lisbon. As of publication, police are still searching for the suspected killer.
