Court upholds conviction that Schaffhausen murdered his 3 daughters

A Wisconsin appellate court has upheld the murder conviction of a man who killed his three daughters at their River Falls home in 2012.

Aaron Schaffhausen, 37, pleaded guilty to killing Amara, 11; Sophie, 8; and Cecilia, 5, but maintained he was insane at the time.

A jury determined he was suffering from a mental disease, but found he knew what he was doing when he killed his daughters. He was sentenced to life in prison without parole.

Schaffhausen appealed, arguing the judge incorrectly told jurors to decide who qualified as expert witnesses and failed to provide expert witnesses' reports to the jury. He also sought a new trial in the interest of justice.

The appellate court rejected these arguments and affirmed his conviction, court documents released Tuesday show.

Meanwhile, the three Schaffhausen sisters are being remembered by a memorial park in River Falls. Construction at the playground began at the end of June, and last week crews began installing some of the playground equipment.
