In Massachusetts if DCF is doing an interview with you, you want to treat it like a deposition, if you have ever done one of those; or consider it in that you want to answer the question assuming you are agreeing to answer it. You don’t necessarily expand a great deal in terms of DCF’s generally not looking to give you credit on a lot of different issues and you don’t want to open up other areas where DCF can then expand the investigation.
It would be important to talk to your attorney either if your attorney is going to be present; or if you are going to be doing an interview on your own about the level of how you want to answer the questions that DCF is asking for. Again, being careful not to provide additional information that may open up to further inquiries. You want to be honest, but do not expand your answers.
