A killer is still at large after a skin cancer doctor was gunned down in the garage of his Brisbane home.
Luping Zeng, 56, was shot in the chest about 11.40pm on Monday while packing his car at his family's MacGregor home.
He was taken to Princess Alexandra Hospital in a critical condition where he died.
Dr Zeng's wife and two adult children were at home when the shooting occurred.
It's believed the pair didn't know each other.
Police suspect only one person was involved in the shooting but say it could be more.
Detectives are searching for a man in a light-coloured sedan or hatchback.
Police have asked for anyone in the MacGregor area, particularly on Delfin Street bounded by Mains Road and Granadilla Street, to come forward with any CCTV or dash cam footage.
They are unable to say what type of gun was used or at what range the shooter fired from.
Dr Zeng spoke three languages and worked at the Waterford 7 Day Medical Centre and Skin Cancer Clinic.
A Brisbane doctor who knew him but asked not to be named described Dr Zeng as a calm and gentle man, and said the Chinese community was rallying around his family.
He had decades of experience, including 11 years in plastic and reconstructive surgery.
Dr Zeng moved to Australia in 2000 and worked in a number of hospitals, going on to work in general practice and skin cancer medicine after studying at the University of Queensland.
His wife is an overseas trained doctor, and their two adult children are also studying to become doctors.
