My son was injured in prison he was beaten while in confinement by another inmate he was beaten so bad that he needed Staples in his head.

Unfortunately this is price paid when getting convicted of felony criminal conduct and going to prison with other convicted felons. While there ARE instances when the DOC can be held liable, such cases are rare and few and far between for a variety of reasons ranging from unsympathetic plaintiffs to juries to inability to control all inmates at all times by DOC to the convict code regarding snitching that forces many witness and victims to claim they fell in the shower to avoid retaliation. You will likely need to hire a lawyer at an hourly rate/retainer at some expense to meet with him and review the issues, see if he is willing ti pursue a civil case and go from there. There may also be some effort to seeka transfer to another wing or location if there are defined risks or exposures for some reason.
