I cannot tell you if you have a viable claim -- what I can say is that you need to sit down with a personal injury attorney to discuss your rights and remedies PRONTO!!
In no way am I offering you legal advice, and in no way has my comment created an attorney-client relationship. You are not to rely upon my note above in any way, but insted need to sit down with counsel and share all relevant facts before receiving fully-informed legal advice. If you want to be completely sure of your rights, you must sit down with an experienced criminal defense attorney to be fully aware of your rights.
Your question sounds simple, but the answer is very complex. No one on this or any other website can tell you everything, or even most of the things, you need to know in order to file a lawsuit. Lawyers study and work for years to learn this. Please do yourself a favor and contact a Dallas personal injury plaintiffs' lawyer right away. Follow the link below to a helpful website.
