A Walla Walla senior saved her teacher by using the Heimlich maneuver while she was choking during class.  Mariam Hart, the fast acting student, was fully trained in CPR because she is in the JROTC program at school according to news reports. When she saw her Fine Arts teacher Julie Laufenburg gasping for air, her training took over and she jumped up and helped her teacher. Even though she is a short 5'2" and much shorter, she executed the Heimlich correctly because of her training.
