Mother of the boys – aged six, eight and nine – said she frantically tried to save her sons from the freezing water

Three brothers ages six, eight and nine have died after falling through ice on a private pond near Bonham, Texas.

The boys’ mother said she ran into the freezing lake and frantically tried to pull her sons from the water, but the ice kept breaking beneath them. The accident happened on Monday.

“They were just screaming, telling me to help them,” Cheyenne Hangaman told the Associated Press. “And I watched all of them struggle, struggle to stay above the water. I watched all of them fight.”

Hangaman, a mother of six, told CBS that she first learned of the tragedy when her daughter ran over to her, shouting that her sons had fallen into the icy pond which was near the house where the family had been staying.
