His name is Brandon Beemer and this is coming from someone who met Martha in Mass at the event. Here is where I read it at: http://martha-madison.com/forum/index.php?topic=888.0
This is what Brandon looks like: http://www.imdb.com/name/nm0066447/photogallery
He is hot and it says that he is in that movie with Haylie and Hilary Duff called "Material Girls." and this to me is a good sign about his acting because any person that has worked with Hilary Duff is good and too work with her that tells you something.

Personally, I think he is too old to be Shawn D, so I am holding out hope this is bogus info. Also, he has guest starred on Days before - as an Assistant DA
