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.

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.
