MINNEAPOLIS (WCCO) — A North St. Paul couple is dealing with the sudden death of their daughter by giving back to the community.

About 150 volunteers helped Tony and Sarah Zahradka build a playground in memory of their 18-month-old daughter, Janie, who died last fall. Doctors weren’t able to say exactly what caused her death.
