How do I get a lawsuit against a false arrest and lost of property and financial losses.

A friend and I were falsely accused of grand theft and were arrested spent some time jail, I lost my truck due to the false charges and I lost income and am continuing to lose income because of the loss of my truck and tools. My truck was impounded and the towing company was trying to hide and keep my truck by claiming they didn't have it for two weeks. The case has now been dismissed after my public defender tried to get me to take a plea of a lesser charge butb I refused because I done nothing wrong. I had a half a load of pallets on my truck before I was falsely arrested and the grocery store owner who accused me took and sold my pallets. So I'd like to start a lawsuit against the grocery store and the towing company.
