[AUDIO] In 911 call, dispatcher helps woman save her choking mother

Janet Williams was with her daughters having lighthearted conversation and a cup of hot chocolate in Laguna Niguel when a marshmallow became lodged in her throat and she was unable to breathe.

Her daughter's 911 call on Sunday morning became a lifeline.

Orange County Fire Authority dispatcher David Paschke was the hero in this scenario, which rapidly became life-threatening for Janet Williams and terrifying for Gina Williams and her sister, says OCFA spokesman Steve Concialdi.

Janet Williams, who is in her 60s, is a retired nurse, Concialdi told the L.A. Times. "Unfortunately her daughters did not know how to do the Heimlich maneuver."

They do now.
