Drinking yourself to death for a Wii

A young mother that past away from water poisoning while trying to win a Wii for her children. A local CA radio station had a contest entitled "Hold your Wee for a Wii." After consuming a large amount of water in an attempt to win the game system (some estimates say she drank almost 2 gallons of water), the young mother told the judges she had a headache and left the contest. A few hours later, she was found dead.

"It appears the DJs involved in a fatal radio contest were well aware of the risks of drinking too much water during a contest in which listeners drank large amounts of water. A mother of three died after the contest on the Sacrament morning radio show." From CBS13

Not surprisingly, the family is suing the radio station for her death but is the radio station really liable for her death? What about personal responsiblity and saying no? The fact that they fired 10 employees over the matter may not look good at trial.
