What punishment will six individuals who committed a brutal murder and get away it have on judgement day?

my friend Patrick was a good man he was very loyal and understanding and exceptionally kind to everyone he worked hard to survive and support his daughter. six years ago six individuals who were known for trouble threw a bottle at his truck when he stopped getting into his truck he was beating unconscious and his truck was driven to a location in the countryside they took his wallet which if they asked him he would have gaven then anything they want. duct taped him into his truck making sure he wouldn't escaped poured gasoline and set the truck on fire with him in it. neighbors near by heard him screaming then a explosion, the judge was too lenient on them they are all out of prison now since 2006, except one who's doing time for drugs - what punishment will god have on judgement day for them for this?
