Tragedy strikes California river: 8-year-old girl dead, 4-year-old boy missing

Rescuers are searching for a 4-year-old boy who was carried away by the current of a California river that was off limits due to high water levels, after his 8-year-old sister was found dead. The children, who were not wearing life jackets, entered the water with their mother and another adult while trying to make their way to climb on a specific rock. Authorities have warned people to exercise caution along rivers where high water levels and stronger flows are creating dangerous conditions.
