(MyFoxBoston.com) – The illegal immigrant who was drunk driving when he hit and dragged a Milford man to his death has been ruled incompetent to stand trial. Judge Janet Kinton-Walker says Nicolas Guaman's "unique cultural background" and language barrier means that he doesn't understand the court process. The court also said that he lacks the ability to consult with his attorney properly. The judge ordered Guaman's attorney to find an interpreter and educate him on the court process.
