Mr Christianos had worked for White as a graphic artist, designing posters to be sold in the killer’s Malvern East shop. He bought Mr Christianos a caravan to live in.
He painted portraits of Sir Donald Bradman and AFL star Gary Ablett snr to turn into posters.
But Mr Christianos would drink, become aggressive and abusive, and the relationship became strained.
White claimed he fired the fatal shots after Mr Christianos threatened him with a knife.
White panicked and stuffed Mr Christianos’ body into a wheelie bin, filled it with bark and soil, and took it to the storage facility he leased to store memorabilia and sporting paraphernalia.
He told Mr Christianos’ friends the missing man had been suicidal, giving them hope he’d one day turn up.
Workers discovered the body after White stopped paying fees on the locker.
The trio of justices who re-sentenced White said a substantially higher sentence was required because of White’s deceptions after the killing.
It had left family in a distressing position.
White will now be eligible for parole after serving at least six years. He had initially been ordered to serve a minimum of 3½ years.
