The bodies of three of the children -- including a 6-month-old -- were found Friday around 12:30 a.m., Redmon said. Authorities continued searching for the fourth child, an 11-year-old girl, he said.
About 75 to 100 law enforcers, firefighters and volunteers were taking part in the search Friday, Redmon said. Some were searching along the creek and others took to the water in boats.
The area is a sparsely populated farming community in far western Kentucky, about 25 miles south of Paducah.
