A body lay undiscovered inside a storage unit in Melbourne for 17 years.
It was only found when the unit's owner, John Spencer White, stopped paying his storage bills, The Age newspaper reported.
White, a memorabilia dealer, has admitted to killing John Christianos in June 2001 and putting his body in storage in the Melbourne suburb of Oakleigh South.
He told police that he shot Christianos, an artist, with a World War II era handgun after an alcohol-fuelled argument and had hidden his body in a wheelie bin.
The bin was locked in the storage unit, where it stayed until July last year. White had told people that he thought Christianos had killed himself.
