 In Maine, the commission in charge of looking into what led up to a mass shooting in Lewiston, Maine, has met once again. Yesterday, a social worker was supposed to appear in front of the panel but never showed up. The commission is trying to find out more about the mental health of Robert Card in the days and weeks before he opened fire at two businesses and killed 18 people and wounded 13 more. Card was later found dead of a self-inflicted gunshot wound.
