Two young brothers died after falling through thin ice on a pond on their adopted parents' farm.
T.J. Frey, 11, and his nine-year-old brother Nate had been playing behind their family's house in Prescott, Iowa, U.S. on Saturday afternoon but failed to return home.
Family members launched a search and discovered the boys' belongings near to a hole in the ice around 20 yards from shore.
Their parents, Tom and Leisa Frey, immediately alerted authorities.
Emergency crews wearing ice suits entered the pond and found one of the boys right away, around one foot under water near to the hole.
They found the other body about 20 minutes later. The brothers were taken to hospital by helicopter, but they were pronounced dead.
Authorities said they do not know what the boys - who were described as inseparable - were doing on the ice, but suspect they were simply playing.
Corning Fire Chief and Adams County Emergency Management Director Donnie Willett told local news: "It was a beautiful day. They were out exploring."
