“If I can’t have her, no one can,” a Hong Kong man accused of strangling his former girlfriend and hiding her body in a wardrobe suggested to a close friend while revealing that he had thought of killing the victim before.
Oscar Mok Chun-yin, 30, also told his friend that he felt “liberated” after killing Dragonair flight attendant Arbe Chan Man-yi, a court heard on Tuesday.
Mok – who killed Chan, 26, in a fit of rage after finding out she had a new boyfriend – told Tsang Sin-yin of a childhood incident that summed up his character after she had guessed what he had done.
“If I could not have something, I would not give it to others,” Mok had told her.
A day after the alleged murder, Tsang recalled getting a call from Mok, who wanted to meet her that night. “He said that something had happened which was quite troublesome,” she recalled.
So they met up. Tsang said that on the way to where they were going for a chat over a beer, she had already guessed Mok might have killed someone.
As soon as they sat down, she recalled: “He said that I guessed right.”
She went on to ask him how he felt. “It was a liberation,” Mok told her. He said he had been having a hard time since Chan split up with him.
A good friend from secondary school, Tsang is testifying in the High Court against Mok, who denied murdering his former girlfriend on December 4, 2013 at her home at Allway Gardens in Tsuen Wan.
Mok and Chan had started dating in 2012 but split abruptly a year later.
Prosecutors allege that after checking Chan’s roster, Mok went to her home on the day of the killing in the hopes of a reconciliation. The encounter took a fatal turn when Mok found out Chan already had a new boyfriend. Mok then killed her in rage, he told police after his arrest.
When Tsang asked him why he was so impulsive, Mok went on to tell a story from his childhood, the court heard.
Mok told Tsang when he was little, there was an incident in which he was fighting over a games console with a younger cousin. The adults sided with the cousin because she was younger.
In response, Mok threw the console away.
Mok told her that he would not let anyone get something he did not have.
When Tsang asked how he killed her, the defendant pointed to his neck and made a squeezing action with his hands.
“I asked: ‘Did she stare at you?’” Tsang recalled. Mok said no, as a scarf was covering Chan’s eyes. He said he knew her body would not have been discovered because her family would think she was on duty.
“I further asked if he could sleep well. He said he slept from 3am till the following day,” Tsang recalled.
Mok does not deny killing Chan, but argued that he was overcome by rage and had lost control at the time of the alleged murder. So instead it should be a case of manslaughter.
But Tsang said Mok told her he had thought about killing Chan on a previous occasion.
The case continues before Mr Justice Joseph Yau Chi-lap.
