The answer to this question is almost always yes.  If someone suspects or has reason to believe that a child is being abused, neglected, or endangered in any way, they can report a claim to the Connecticut Department of Children and Families (DCF).  In situations where someone is arrested for risk of injury to a minor, the police will almost always follow up with a call to DCF.  A complaint about child welfare typically will lead to an investigation by DCF.
