This happened with my case. My ex's boyfriend accused me of trying to run him over. the prosecutor refused to drop the case and kept sending his lacky. He never went over our discovery and said he would do it. So he kept asking for a continuance from the judge. This shit went on for over a year with 5 court appearances and a bunch of wasted time for my attorney and I.
On the police report
Police noted he was under controled substances with his friend
Multiple descriptions of vehicles
Multiple descriptions of a suspect
I had GPS records of where I was exactly that night and all day.
Eventually his lacky had enough and accepted our motion to dismiss.
