Chan being sexually assaulted before her death not conclusive

A chemist of the government laboratory told the Chan Yin-lam inquiry by the Coroner's Court that there are no conclusive evidences whether student was sexually assaulted

The naked body of Chan Yin-lam, 15, was found floating last year not far from the Hong Kong Design Institute in Tiu Keng Leng, where she studied. 

Government chemist Wai Wing-kong, who examined Chan’s viginal specimen, said there was no semen, all DNA results came back to be Chan’s only.

Wai also claimed there were bloodstains in Chan’s nails. From the DNA sample collected from the nails on her right hand, it came back also belonging to Chan’s.

Forensic pathologist Li Yuk-wah also testified in the inquiry, claiming there were no bruises on Chan’s reproductive organ.

However, Li claimed that it is not common that people who experienced sexual assaults, including rape, leave bruises on their intimate parts. Therefore she cannot conclude that Chan has not been sexually assaulted before she died.

Li also pointed out that it is not common for a person to commit suicide given that person is good at swimming. She also could not explain through autopsy why Chan’s body is fully naked when found.

Officer Li Ho-kit, who edited surveillance videos for the investigation, also testified in the inquest. He said that Chan held a leaflet from the Hong Kong Federation of Youth Groups while she was wandering at the school on the night of Sep 19. 

However, she was not a member of the federation, he noted. 

The jury noticed a gap of ten minutes of Chan’s whereabouts in the footage, hence requesting the court to enquire the school, which was agreed by Coroner Ko.
