MADISON COUNTY, Ark. (KTHV) – The search for two young Madison County children who were swept away in floodwaters Saturday has changed from a rescue to a recovery effort.

CBS affiliate 5NEWS reports that a 38-year-old woman and her four-year-old boy and 18-month-old girl were stranded in high water in the Hindsville area after water swept their vehicle off the roadway and over a low water bridge.

First responders say the mother tried to save the kids but the current was too strong. Emergency workers found the woman downstream, but the children were not found. The woman was treated on scene but refused to go to the hospital while the search continued for the children.

Madison County Sheriff Rick Evans said they had people in Glade Creek as well as on the banks searching for the children.

At one point, a helicopter was called in to search an area of the creek that is harder to get to.

On Monday, the search switched to a recovery effort, although workers are still hoping for the best.

“Right now we’re probably looking at a recovery effort," said Evans. "The way things happened and I hate to look at it that way but we’re hoping for the best.”

He said crews did locate some clothing they believed to be from the truck the children were in but there is no sign of the children themselves.

A family friend has set up a Go Fund Me account to help with the children's funeral expenses.

The search will continue until it gets dark. Stay with THV11 and for more details as they become available.
