Sorry for your loss.  Though I didn't know him I've lost ones I love in death also   I know it hurts. I have found comfort in Gods promise at Revelation 21:4 which says, "And he will wipe out every tear from their eyes, and death will be no more, neither will mourning not outcry nor pain be anymore. The former things have passed away."   This is a promise from Jehovah God. www.jw.org.
