David James Elliott! (Hey, we bet if we asked your grandpa, he'd know who we were talking about!)
David famously starred in the long running CBS series JAG and now is back to joint the cast on CSI: NY. He'll be playing the ex-husband of Sela Ward's new investigator, Jo Danville, and will debut sometime in January as his episode is shooting now!
How fun! Maybe he'll get to stay for another episode- if he is any good!
