Thank you so much. I have added some additional comments.
On a Misdemeanor charge, the State would have to bring charges against you within one year. This would be 90 days if there were no waiver of speedy trial.
The State may be filing Felony charges which would have a longer Statute of Limitations to circumvent this problem. If this were the case, and there is no evidence of Felony Battery which would require serious bodily injury then there may be something here to explore. It definitely sounds sketchy.
In Dade you would not really be able to waive your right to a speedy trial at your first appearance. Is this case from Broward? Palm Beach?
Again, these are very unique circumstances and I would strongly recommend that you consider the hiring of a lawyer.
