I think you should write him a very polite letter, asking some carefully thought-out, specific questions about the case.  Clean it up, print it out, sign it, put it in the mail.For a lot of people, sometimes things have to show up in black and white to register properly.  That includes lawyers.  But letters work well for attorneys, who routinely keep almost every single piece of paper, and most certainly any letter, that they get on a case.  There are some lawyers, unfortunately, who do blow off phone calls, but very, very few who will treat a letter the same way.
