Now the nest step is an Appeal. Hire a Criminal Appaelate attorney!
My name is Stephen R. Cohen and have practiced since 1974. I practice in Los Angeles and Orange County, CA. These answers do not create an attorney client relationship. My answers may offend I believe in telling the truth, I use common sense as well as the law. Other state's laws may differ.. There are a lot of really good attorneys on this site, I will do limited appearances which are preparation of court documents it is , less expensive. However generally I believe an attorney is better than none.
What can "we" do?
Your uncle can (1) appeal his conviction to a reviewing court which will review the record for legal error and has the power to order a new trial or, in an extreme case, to vacate his conviction altogether and order his discharge; (2) petition for collateral review of his conviction before the original trial judge for consideration of new material outside the record; (3) both, if appropriate.
Everybody else can contribute to a fund to pay for the very considerable amount of highly skilled and specialized legal (and possibly also expert and investigative) work that will be required for 1, 2 and 3.
The next step is to hire an appellate attorney. They will know how to review the record for legal grounds for appeal.
