Doctor tells inquest how 10-year-old's legs were twisted when she arrived at hospital

The fingerprints of a 10-year-old girl who plunged to her death were found on the upper floors of her school in Kwai Chung, an inquest heard yesterday.
Sergeant Chong Kin-keung, who specialises in fingerprint detection, said he extracted four fingerprints when he went to CCC Kei Chun Primary School at about 10.40am on December 9, 2013, to investigate Law Cheuk-ki's fall.
Law was found in the school playground shortly after 7.30am that morning and showed no signs of life.
"Three fingerprints were found on the stairwell connecting the fifth and sixth floor," Chong told the Coroner's Court.
He found one more on the same stairwell, facing the playground, on the seventh-floor section leading to the roof. Of the three on the lower floors, two belonged to Law, one from each hand. The other two remained unidentified.
Forensic pathologist Foo Ka-chung said most of the injuries were sustained on the girl's back.
