The sad truth is that innocent folks get railroaded, even “on hearsay” without corroborating evidence. Sometimes, as it appears in your circumstances from your limited proffer, the stakes are so high that a plea to a reduced charge is the most prudent course of action. However, no cyber-lawyer (someone like me, who is on a computer operating on extremely limited information) can responsibly advise you as to whether or not you should take a plea or proceed to trial.
If you are facing felony charges then you have a lawyer. Your lawyer, whether public or private, needs to take whatever time and effort is necessary to view and challenge the State’s evidence against you (hearsay and otherwise) and then compare and weigh the same against the relative strengths and weaknesses of the defense case. This takes skill and effort, and most importantly, time.
I understand your aggravation and frustration but you are best advised to expend your resources on assisting your lawyer to prepare a meaningful and effective defense as opposed to seeking answers online from folks who are essentially incompetent to advise you in your case.
You may or may not enjoy viable defenses to the charges, affirmative or otherwise, or there may be factual, legal, procedural or substantive mechanisms by which to attack and beat the charges in your unique case, I do not know and the forum to find out is NOT on line; rather it is in the sanctity of attorney’s offices, where your statements are privileged and cannot be used against you.
I hope that I have been helpful in answering your question.
