wrongful in prisonment

Son was sentenced to prison on charges of sexual conduct with a child. Was told to take a plea by attorney. There was never any investigtion every done into either parties. How do we go about getting help to get him out of prison? Attorney tried to convince us that person is guilty of the offense. We just need help to prove that he did not commit this crime against a child. We don't think lawyer had best instrest on son in court. How do we go about proving or getting help to prove innocence of son.

possible assaut/unethical business practice

I received a phone from the dentist office. The lady stated my wife's insurance would not pay for one of the procedures. I blurted out Jeus Christ. Why, because I had been told several times by Joe, another office worker that all was okay. She hung up the phone. I went to the office to talk to Joe. I asked who called me and he pointed to a lady. Joe and I were talking and she interrupted. I asked to stay out-of-it. Joe and I were discussing this clamly. He was about to give me a phone number of who to call when the door opens and a fellow states,'' Is the guy here who was yelling at my wife?''. I said I'm he but I didn't yell at your wife. He walked toward me with his finger in my face and said don't yell at his wife: that she was ''crying''. He continued to verbally harass me. Then a lady asked him to leave. Do I have any recourse in this matter against the office and/or the man who threatened me? I never yelled at the lady. I only asked her to stay out of our conversation since she had hung up on me earlier.

Summons/Notice

I got a summons/notice to appear for a mediation conference at county courthouse, if I didn't come I would dedault, was there at appointed time, was called to assembly room to meet with paintiff's attorney and mediator, was told the attorney firm for the plaintiff had called about 1/2 hour earlier to ask for a continuance, it was denied, they didn't show up, there were 3 different defendants there for that attorney and about 12-15 no shows, the summons stipulates that the plaintiffs must appear to avoid have the case dismissed for lack of prosecution, what should I do now, and what can they do now?
