I see what has happened now.
Essentially, the lawyer did not want to appeal. Appealing a criminal conviction, especially something serious like this, is something that is practically automatic in the practice of criminal defense. It is an appeal of right, and he will still be able to get the appeal. It will just take longer to do it.
He will need to file for what is called "post conviction relief
" and will be able to show that his lawyer was ineffective in not pursuing an appeal. The court will then grant him time to file a Motion for New Trial and appeal.
If you retained this lawyer, you will likely have to retain another one to pursue this. If this lawyer was appointed / public defender, go ahead and contact the public defender's office and tell them your son never got his appeal and would like to pursue a post-conviction petition. They can guide you in the right direction.
