i think this is publicized to the point where if anyone wants to have a memorial service for the guy, they can just step forward and at least give him a pauper funeral in a plain pine box. if absolutely no one steps forward to do this, and the guy left no will, than they should just cremate the guy or bury him in a pauper cemetery. by "his family" do they mean only the incarcerated wife and mother, or some "free" family? do the wife and mother have any way to "claim" him from jail if they want?
if no one claims him, i think it might be best to cremate the guy because a grave site for a high profile murderer might invite vandalism, which i assume a pauper cemetery is not set up to handle.
