A man who stabbed his ex-girlfriend to death on a bus in 2017 was sentenced to life imprisonment, the High Court ruled Thursday.
Ng Yan-kin, 26, was convicted of murder last December for killing a 20-year-old woman, surnamed Li, on a bus before smashing a window and jumping out. The court earlier rejected his guilty plea to manslaughter, which is a lighter charge.
In the ruling, Judge Audrey Campbell-Moffat said Ng poses a great risk to society.
According to local media, the victim ended the relationship with Ng, who overbearingly controlled her life and forbade her from joining activities at the university she was studying at.
After the break-up, Ng began hurting himself and threatening to release sex tapes that the couple had taken together.
The judge believed the murder was premeditated because the man bought the knife out in advance and placed it in his backpack.
Security footage from the bus, which was in Chai Wan, also showed Ng putting his hand in the backpack, as if waiting for the moment to attack his ex-girlfriend.
After punching Li and stabbing her more than 30 times on the upper deck of the bus, Ng knifed himself and jumped out of the bus through a window that he broke with an emergency hammer.
The victim’s lungs, heart, and sternum were damaged and she was certified dead soon after being sent to the hospital.
Citing mental health issues, Ng said he did not remember the attack.
The defence argued that Ng suffered from depression and unstable emotions at the time of the attack.
In a mitigation letter, Ng’s father admitted neglecting his son, saying that he may have ignored his mental health as he was focused on supporting the family.
His former teachers also wrote a letter, saying that Ng had good conduct at school.
