A 12-year-old Mill Valley girl is being hailed as a hero after she helped save the life of a toddler who fell into a swimming pool.

Kara Waluk was playing with her sister at about 4:30 p.m. Sunday in the backyard of their Mill Valley home when she noticed a 2-year-old playing in a nearby backyard on Starboard Court. The little boy had a stick and was playing with the pool water. Kara looked away for a minute and when she looked back, the child was floating face-down in the pool, according to the Marin County Sheriff's Office.
