A home in Queensland's Lockyer Valley is being searched as police look for evidence that could lead to a breakthrough in the disappearance and suspected murder of Sam Price-Purcell.
Mr Price-Purcell was last seen in the Brisbane suburb of Mitchelton in February 2015 as he got into a yellow 2010 Holden Commodore SS sedan and it's believed he travelled to the Toowoomba area.
A Queensland Police spokesman said the Helidon home once belonged to people with potential connections to Mr Price-Purcell and was being searched on Thursday morning.
Police are expected to look for personal items which belonged to Mr Price-Purcell and other evidence suggesting he visited the property.
It's the second search in two months in the Darling Downs region with a Leyburn property searched in March.
Officers found a number of items, including firearms and some drug paraphernalia, which was taken for further investigation.
The initial search followed a tip-off which came after an emotional appeal from the missing man's mother Leoni Price.
"We need to know what happened so that we can have some peace," Ms Price told reporters at the time.
"The emptiness that I feel, his loss has just left a massive hole in our hearts."
Detective Senior Sergeant Michael Jones is to address the media later on Thursday morning.
