The deadly incident unfolded Tuesday afternoon at the popular Franconia Falls in Lincoln, New Hampshire, when Bagley’s 10-year-old son slipped and fell into one of the pools near the falls, according to the state Fish and Game Law Enforcement Division statement.

“He could not get out of the pool as it was a fast, circulating current. The mother jumped into the river to help her child and began to immediately have trouble,” according to the statement.

The two other Bagley children, one an 18-year-old, dove into the water in an attempt to rescue the mother and brother, officials said.

“They were able to get their brother out of the water, but in doing so, another brother became lodged in the boulders and could not escape,” according to the statement.

Sean Bagley also dove into the water in a desperate attempt to find his wife, officials said.

“He eventually found her on a rock and immediately began CPR. Unfortunately, she was unable to be revived,” according to the Fish and Game Law Enforcement Statement.
