Mercy Hospital's training, preparation lauded in wake of shooting incident

More people could have been shot at Mercy Hospital last Monday if not for the quick action by police and the preparedness of hospital staff, who only recently had reviewed how to respond to an active shooter, experts say. In the Nov. 19th incident, which unfolded over minutes, three people — Dr. Tamara O’Neal, pharmacy resident Dayna Less and Chicago Police Officer Samuel Jimenez — were killed by O’Neal’s ex-fiancé, Juan Lopez. Lopez died in a shootout with police.
