A woman at the front of a "human chain" trying to rescue swimmers in distress on an Alabama beach tragically died after the chain broke and she was left struggling in the rough waters. Karen Graham was on a vacation with her best friends when they heard two women scream out for help in the water. More than 20 people formed a human chain that stretched to the distressed swimmers. Then, the chain broke and swept many of the rescuers, including Graham, into the surf. Sadly, she did not survive.
