Police are looking for 39-year-old Lee Hillier (pictured above) over a fatal stabbing at Murrumba Downs.
Hillier - is a person of interest - after 41 year old Nathan Frazier died from stab wounds to his head and chest near a convenience store on Blyth Road yesterday:
"He's shown a propensity for violence -- he's one of four questioning for this offence.
I would ask that people do not approach him, I ask that they call Triple 000 and if they've got any information on his whereabouts to contact Crime Stoppers - if it's urgent go through Triple 000".
That's Detective Inspector Damien Hansen. It's been revealed Hillier served four and a half years in jail for a dramatic siege in the Queen Street mall a few years ago.
