One of two men charged over a cold case murder in south-west Victoria has allegedly told police how the victim was killed, and where the body was buried.

Christopher Jarvis went missing from his home at Wangoom near Warrnambool on June 13, 2006, but a tip-off from the public led to the arrests of Glenn Ernest Fenwick, 59, and Steven Frederick Johnson, 71, in November last year.
