There is no guarantee you will be able to find a lawyer to help you, but here are the places you can look. You will have to make appointments by phone and then go to them. There will be lots of appointments and lots of rejections before you are likely to find someone to help you, but don’t give up!
Prepare a SHORT document where you write about your case and send it or deliver it to the attorneys or law clinics you made appointments with before you go to your appointments – with a cover letter that is a few sentences saying this is what you are doing.
Write a one to two page story about your case and attach any evidence that proves you are innocent (affidavits or letters from witnesses or whatever else you have). Give the details of what you were accused of and what you confessed to and pled guilty to. Write a paragraph as to why you pled guilty when you didn’t do it. Write a paragraph about what you plan on doing in life and how the conviction is preventing you from accomplishing your goals. Write a paragraph about what the state’s witnesses said that caused you to be convicted and why you think they were motivated to lie. Give this to each of the places you get an appointment BEFORE you go to the appointment.
Contact law school clinics where they have lawyers who represent indigent clients. They all don’t do this automatically and they are limited by funding from grants and government. etc. But call each one and pound the pavement meeting with them after making appointments and showing them the evidence that proves you are innocent. This is NOT an easy task.
You should also apply for executive clemency from the parole board – which reviews your case and recommends to the Governor if you should be granted a pardon. Make sure you answer the above questions in your written application. The Gov. can overturn any conviction with a pardon. It would be better if you could find witnesses who can prove your innocence and get a signed affidavit from them that would be signed by a notary. Remember that letters are hearsay and not admissible in court. If you have witnesses that sign affidavits that state they are willing to testify to what they wrote in their affidavits that would be best.
