Baffled Hong Kong police hunt for clues after mother and daughter found dead in parked Mini Cooper
Tributes to wife and daughter of professor as it emerges he bravely continued his work in the hospital where the women were declared dead

Detectives will scour a yellow Mini Cooper in which a mother and daughter died on Friday to find any clues that may shine light on their mysterious deaths as tributes poured in for the Sai Kung family.
Sha Tin district officers will analyse the car, in which 17-year-old Lily Khaw and her 48-year-old mother were found unconscious on Friday in Ma On Shan.
The news came as it emerged the grieving husband and father continued his vital work as a senior anaesthetist on Friday night - hours after they were declared dead in the same hospital.
The women were the wife and daughter of Professor Khaw Kim Sun, a hugely respected member of Chinese University's department of anaesthesia and intensive care who works at its teaching hospital, Prince of Wales.
A source at the Sha Tin Hospital said Khaw continued his duties hours after his wife and daughter were declared dead.
