I'm Doug, and I'm very sorry to hear of your situation. My goal is to provide you with excellent service today. I am not trying to scare you by what I am about to say. I say it because I have seen this many times before. I have been an attorney for more than 3 decades.
My answer to you is comprised of 3 words. Don't Do It! Do not voluntarily go in to speak to the police. In this situation I can virtually guarantee that you are a target of their investigation. What probably happened was that a neighbor, teacher or someone else reported to CPS that one or more of the children was molested. The parents and the live-in adults are always the persons looked at first, and foremost.
The fact that the police now have this investigation and you are not being called into CPS is another huge red flag.
I urge you in the strongest way to immediately retain a local criminal defense attorney. The next step---when you don't voluntarily go in to the police department----will likely be an arrest warrant being asked for to a local judge, for your arrest by the police. Also, if you do go in for questioning, there is also a very good chance that you will be arrested at the conclusion of the interrogation. I have personally seen this work this way and I know what I am talking about, so give heed. Get yourself an attorney and speak to no one else about any of this situation. You need to protect you, and right now.
