Updated at 4.59pm: Police and transport engineers on Wednesday inspected the scene of a car crash that killed three cousins on Christmas Eve in Lantau. No mechanical defects were found on the car or the bus which collided head-on with it in South Lantau Road near Nam Shan, according to police report after the inspection at the vehicle examination centre in Siu Ho Wan, North Lantau. Post-mortems on the car's driver Ho Wing-kit, 20, and Ho Ka-kei and Ho Kwok-bong, both 17, were also conducted but the results will not be available at least for another month to allow for toxicological tests.
