Cps was called saying I had sex with my 9 yr old son. He was questioned twice alone once with his mom. His mom was questioned twice and me once. He said he never said anything like that they even made him cry. He had a physical exam that proved nothing happened. Now they want me to take a lie detector test next week because the officer isn't happy with the results. I hear they are not accurate and am deeply afraid of losing my family over this horrendous allegation. What are my legal options how do I prove my innocence and start to rebuild my family? He will not stop till he gets what he wants.
