RIVER FALLS, Wis. -

The mother of three young girls killed by their father in River Falls says she tries to focus on the joy her daughters brought to the world.

Jessica Schaffhausen says she tries not to think about how her girls died, but rather how they lived and the personalities that made them unique. She talked to the Star Tribune about her daughters.

Jurors last week said Aaron Schaffhausen had a mental defect but is still responsible for killing the girls.

Eleven-year-old Amara was a budding scientist who watched MIT lectures online and brought home report cards filled with `As.' Eight-year-old Sophie often had an artist brush in her hand, always messy with paint or chalk. Five-year-old Cecilia loved listening and critiquing music and tried to keep up with her old sisters.

Jessica Schaffhausen said she is grateful for the kindness and support of friends, family and even strangers.
