Marlon Jackson -- God Will Punish Conrad Murray

Michael Jackson's older brother Marlon wants Judge Pastor to throw the book at Dr. Conrad Murray today -- but he insists Conrad's real punishment will come from God himself.

Marlon flew in to LAX yesterday -- presumably for today's sentencing hearing -- and told us he hopes Murray gets the maximum sentence ... but explains, "The real verdict will come down not on planet Earth ... the Lord will take care of what he needs to take care of."
