One year on, Florida remembers victims of Parkland school shooting

Students, parents and politicians marked the first anniversary on Thursday of the Valentine's Day shooting at a Florida high school with prayers, somber tributes and calls to action. Marjory Stoneman Douglas High School, where a former student killed 14 classmates and three staff members a year ago, cancelled classes for the day and offered counseling services instead. "Exactly one year ago, to the minute at around 7 am, I sent two kids to school," said Fred Guttenberg, whose 14-year-old daughter Jaime was among those killed at the high school in Parkland, Florida.
