(BRANSON, Mo.) -- A tourist duck boat capsized in a lake near Branson, Missouri, during powerful storms, killing at least 11 people, including children, officials said.
The Thursday-night accident also injured seven people and has left at least five others missing, Stone County Sheriff Doug Rader said.
The region suffered severe evening thunderstorms, including winds in excess of 60 mph. The conditions are believed to be what caused the boat to sink to the bottom of the lake.
Eyewitness video showed the craft, which travels on land and water, taking on water as waves lashed at its sides.
"The wind really picked up bad, and debris was flying everywhere,” Allison Lester, who was on a nearby boat, told Good Morning America on Friday. "The waters were rough.”
Lester's boyfriend, Trent Behr, added, "We actually heard the captain say the boat flipped or the boat was sinking.”
Behr saw a woman lying in the water where he ran down to help, he said.
"We eventually did pull her up onto the boat," Behr said. "She was unconscious. I was about ready to start CPR, and the EMT did show up at that time."
Suzanne Smagala-Potts of Ride the Ducks Branson, the company involved in the accident, said in a statement, "We are deeply saddened by the tragic accident."
"This incident has deeply affected all of us," Smagala-Potts said. "We will continue to do all we can to assist the families who were involved and the authorities as they continue with the search and rescue. The safety of our guests and employees is our No. 1 priority."
