Nearly 50 police and State Emergency Services volunteers spent Saturday 2nd January 2010 combing an area in Eden Hill after firefighters found a skull and vertebrae on New Years Eve after a fire at Success Hill Reserve exposed the bones. Northshore SES provide one full search team, who were on site for the whole day.
It may take police forensic officers and an anthropologist up to a week to identify human remains found in Perth bushland.
Police will attempt to identify how long the bones have been at the site and the cause of death.
Firefighters were called to the area to attend a small bushfire when they stumbled upon the remains. Subsequent searches involving police unearthed more bones including vertebrae.
A police spokesman said Major Crime Squad detectives were investigating the discovery and the death was being treated as suspicious.
It has been reported that the remains are those of a Caucasian male but a police spokesman said it would be days before the persons age or sex could be confirmed.
The bones could have been at the reserve for up to a decade.
