Two parents of children who were killed at Sandy Hook School are headed to Washington state, the site of the latest school shooting.  Mark Barden and Nicole Hockley, whose sons Daniel and Dylan died on 12-14, are travelling to Washington state. 

Last week one student shot and wounded five peers, two fatally, and took his own life.  There is a ballot initiative in Washington state expanding background checks on firearm purchases. 

The parents formed The Sandy Hook Promise shortly after they lost their sons to share their stories with others and to help put an end to gun violence.  Barden says they will be there to honor children who have had their lives cut short by gun violence, to share their stories and to urge Washington residents to vote for the ballot initiative.
