I've had a similar experience. Though not nearly this bad. My ex, who was an illegal accused me of DV. In spite of the fact that responding officers having let me go from her apt, she found a female "detective" who was willing to push charges on me. By the time I managed to get the case settled with a reduced conviction I was nearly broke from the legal expenses and basically homeless living with friends. I should have recognized her manipulative nature.
Her ultimate motivation? If she acquired the status as a DV victim, it would have given her asylum in the US. It's of little comfort that she was deported. The police and DA's are not there to pursue justice, they are there to convict you. Even if they find out later they're wrong, they'd rather see you rot or suffer than admit it. I wish I has Mr Gonzalez's finances or I'd fight for full vindication.
Regardless I'm happy he was ultimately vindicated, but I'm sure it's of little comfort to him that having suffered this trauma, the "woman" who caused it remains free and has the opportunity to further manipulate his son. She should be in prison for the maximum sentence Mr Gonzalez would have faced.
So guys and gals, if you recognize mental problems in a partner, stay away. Stay far away and never look back.
Perhaps having video cameras up everywhere might not be so bad in some circumstances. At least if they can be used to prove you weren't doing something someone accused you of.
