Divers recovered the body of a 9-year-old boy killed in a helicopter crash at the Lake of the Ozarks Sunday night.

State Water Patrol Captain Matt Walz says divers found the body of Zachary West of Eureka still in the wreckage. He couldn’t free himself from the helicopter after it crashed into the lake. The pilot, another adult and two other children did manage to escape the chopper and swim to the surface where boaters rescued them. None of the survivors suffered serious injuries. Walz says none sought hospitalization.

The helicopter is being pulled from the lake. The wreckage will be stored in a state facility for officials with the National Transportation Safety Board to inspect.

Walz says witnesses have told the patrol that the helicopter was hovering over the surface of the water when it began spinning out of control. It spun in circles several times before crashing into the surface of the lake.
