I watched "Dear Zachary: A Letter to a Son about his Father" last night, which some friends had recommended.
What a sad story. From IMDB:
"In 2001, Andrew Bagby, a medical resident, is murdered not long after breaking up with his girlfriend. Soon after, when she announces she's pregnant, one of Andrew's many close friends, Kurt Kuenne, begins this film, a gift to the child. Friends, relatives, and colleagues say warm and loving things about Andrew, home movies confirm his exuberance. Andrew's parents, Kathleen and David, move to Labrador where the ex-girlfriend has gone. They await an arrest and trial of the murderer. They negotiate with the ex-girlfriend to visit their grandchild, Zachary, and they seek custody. Is there any justice; is Zachery a sweet and innocent consolation for the loss of their son?"http://www.imdb.com/title/tt1152758/
