RIVER FALLS, Wis. (AP) — A mother has gotten her first up-close look at a playground built in memory of her three young daughters killed by their father in northwestern Wisconsin in 2012.

Reports say the playground built for Jessica Peterson’s daughters Amara, Sophie and Cecilia is set to open Aug. 15 in River Falls. The universally accessible facility named the Tri-Angels Playground cost about $550,000, and Peterson says volunteers and donations made its construction possible.

Peterson says the playground has equipment specific to her daughters, including a microscope and slides that look like shoes.

The girls’ father, Aaron Schaffhausen, is serving three life sentences for their deaths. Peterson has married again, and has a 15-month-old daughter named Trinity and a newborn son named Flint.
