Our boats, along with several other agencies’ boats, are currently conducting a grid search utilizing sonar and other tools to try to locate the father,” Sacramento County Sheriff’s Sergeant Shaun Hampton said. Officials say the kids and their father were in a boat when a 1-year-old fell overboard. “A father subsequently dove in after the child attempting to rescue the child from floating down the river,” Hampton said. The man’s 10-year-old daughter quickly thought to dial 911 from her father’s cell phone. The 1-year-old , was flown to UC Davis Medical Center and is said to be in critical condition. Officials credit the life vest the child was wearing for the quick save, but don’t believe the kids’ father was wearing one. Hampton said the water is cold and moving quickly with lots of debris, which is a dangerous combination for a distressed swimmer. Crews have called off the search for the night but will resume at 7:30 a.m. Saturday morning.
