Police to probe Ivan Milat over homicides

NSW Police are preparing to speak to backpacker serial killer Ivan Milat about his crimes and unsolved homicides he is linked to as he battles terminal cancer.

Milat was taken from Goulburn's supermax jail to the Prince of Wales Hospital in Randwick earlier in May for medical tests, where he remains. He is dying from oesophagus and stomach cancer.

AAP understands NSW police are preparing to interview the 74-year-old.

Milat has never confessed to killing seven backpackers and has maintained he is innocent.

Milat's nephew, Alistair Shipsey, told Network Ten earlier this month his uncle's condition is "very bad" and he has a couple of weeks to live.

Milat - who's reportedly lost 20 kilograms in recent weeks - hasn't been able to eat or keep food down.

The former road worker was sentenced in 1996 to seven consecutive life sentences for murdering seven backpackers whose bodies were found in makeshift graves in NSW's Belanglo State Forest in the 1990s.

He also kidnapped British tourist Paul Onions who managed to escape from Milat's vehicle.
