What attorney handle this type of case?

Criminal defense attorneys handle matters like this. Since you had a preliminary hearing, I'm guessing you have an attorney. I hope you're not making the terrible mistake of representing yourself.

You need a criminal defense attorney, obviously, since the matter was turned over to the police.

So what happened after that did the case get dismissed? What exactly is your question? What exactly do you want?

A criminal defense attorney would handle a robbery case.

Friend, you are going to need more going for you then these facts. I'm certain some type of discourse was made the day that you were stopped, along with the LP's version of facts so the missing tape may be of insignificance. Since it was a felony this case isn't going away easily. Before spending any further time on the Internet, you could benefit from meeting with a criminal defense attorney to discuss specific facts in an attorney-client privilege environment, which the Internet is not. Even if you decide not to hire the attorney the consultation with him or her could help you to understand the issues and your options. Many reputable attorneys offer a free consultation. I wish you the best.
