This is my second Lethal Weapon story. And this time, it's Roger Murtaugh's turn to find out about unknown member of his family that he never knew about. Murtaugh has a twin sister named Destiny Murtaugh. Their mother had put her up for adoption at birth. And Murtaugh never knew about her. When, Riggs learns about her existence. It isn't long before he blabs it to Murtaugh. And the two go on a action packed journey to reunite Murtaugh and his twin sister.
