CONCORD, N.H. (AP) — The father of a murdered toddler has reached a court settlement with a child advocacy group while his lawsuit against the state's child protection agency moves forward.

William Boucher's 3-year-old daughter, Brielle Gage, was beaten to death by her mother in November 2014. The state Division of Children, Youth and Families had investigated Katyln Marin 10 times, including for beating her oldest son with a studded belt, but returned the children to her months before Brielle's death.

The Concord Monitor reports that nearly all documents in Boucher's lawsuit filed in November are under seal. An attorney representing Court Appointed Special Advocates of New Hampshire told the court last week that the organization has reached a confidential settlement with Boucher.

Marin is serving a prison sentence of 45 years to life.
