HOUSTON (AP) — At least three people are still missing after torrential rain in Texas and Kansas this week led to flooding rivers, washed out roads and left four people dead.

In Kansas, the search for a missing 11-year-old boy was suspended late Saturday because of darkness and the fatigue of first responders, according to Wichita Fire Department battalion chief Scott Brown. The boy was swept away in a swollen creek on Friday night.

Near Austin in Travis County, Texas, officials planned to resume aerial searches on Sunday for two missing people whose vehicle was swept off a flooded roadway after the area got 9 inches of rain, said emergency services spokeswoman Lisa Block.

Four people have died in Texas from the flooding.
