Kids in state custody ran away more than 3,400 times over a three-year period, according to figures obtained by Boston’s WBZ-TV.

Some of those children ran away repeatedly, while 30 of the kids were missing for a year or longer, the records show.

The WBZ I-Team received the data from the Department of Children and Families (DCF) 10 months after making a public records request in January for all runaway incidents from 2013 to 2015. Along with the date the child went missing, the records also show how long children were gone before being returned to their DCF foster home or other residential placement.

The I-Team has also learned DCF just implemented its first policy devoted to children on the run. The set of guidelines spells out when to contact police, launch search efforts, and identify kids who are at a high risk to run.
