Lewiston, Maine, is in mourning after last week’s shooting that killed 18 people. Along with the grief, there’s growing scrutiny about why law enforcement didn't find or stop Robert Card before the shooting. Friends, family and the Army Reserve all reported concerns about his behavior and access to guns months before the shooting. Laura Barrón-López discussed more with Margaret Groban.
