LISTEN: Police speak about new leads in Wallman murder case
POLICE are pursuing fresh information into the disappearance of Marilyn Wallman case.
They're asking members of the public if they saw an aqua and white HD or HR Holden on Mirani Mt Ossa road in 1972 or anyone who would've owned this type of car at the time.
The car was seen on Wallmans Rd on the day of her disappearance March 21, 1972.
Following the positive identification of Marilyn's skull fragments last year police took statements from people who had never been interviewed in relation to the case before.

Police said the site on Mirani-Mount Ossa Rd where forensics were stationed last week was previously used as a rubbish dump.
They asked if anyone had picked up the watch from the site.
Marilyn's two brothers and parents were at a police press conference today in Mackay to announce the new lead.
Police were 'digging for days' at the site where Marilyn Wallman's skull fragment was previously found.
A CIB spokesman said police and scientific officers are at a property on Mirani-Mount Ossa Rd near McGregor Ck.
He said they're just past the creek and officers are taking soil samples.
