My name is Ben. I'm a licensed attorney. Glad to try and help out.
Sure sorry for the painful circumstances, truly. My heart goes out to you.
There is a particular federal statute, namely 42 U.S.C. § 1983, which provides a remedy for those wrongfully deprived of civil liberties by one acting under color of law, such as a police officer. Having carefully read and considered everything you posted, here is what I would recommend based on the information you have shared. I would have the case screened on the merits by a plaintiffs' trial attorney. If an attorney accepts the case pursuant to the customary contingency fee agreement there would be no up-front charges to you. Rather, your legal counsel would only get paid out of the proceeds of a verdict or settlement if he or she were successful in obtaining a favorable outcome and winning the case on your behalf. This can only be done through having a lawyer review your circumstances, meaning it cannot be done in this online informational venue. In other words, you have done all you can do, your next step at this juncture is to confer with legal counsel, but the good news is that process is entirely free of charge to you.
I can only imagine what a stressful and trying time this is for you, so please believe me I mean it when I say I am glad to say there is a way to seek justice without having the burden of trying to pay attorneys' fees . To help folks in this online venue, I am required to follow site rules including refraining from accepting cases and/or making direct referrals to named attorneys. However, I can tell you where I would turn were I in your very shoes. Toward that end, my very next step would be to take advantage of the resources of the non-profit, American Bar Association accredited, National Board of Trial Advocacy Division of the National Board of Legal Specialty Certification. Here is a listing of all such Board Certified Civil Trial Advocates practicing in the applicable jurisdiction (please just click the following link):
Without competent legal counsel, I don't believe you will get anywhere at all. I wish the system was friendlier, and I hate to offer that opinion, but I just feel you deserve to hear the truth rather than being misled.
If you have a follow-up question or need clarification, please just say the word by using "reply" to reach me.
I hope all works out for you and your family.
