Police want help to solve Qld man's death

A white car may provide clues about the death of a man in southeast Queensland earlier this month.

A friend found the 60-year-old man unconscious at his home at Nanango, west of the Sunshine Coast, on September 11.

He was taken to Kingaroy Hospital where he later died.

Police are asking anyone who saw anything suspicious near the house or a white vehicle at Old Esk North Road to come forward.
