Ms Lo could hardly bear her sorrow when she received the call that her husband had died in a car accident. Her pain quickly turn to shock---- the car involved in the accident was driven by a friend. That friend, Henry Lee, had chosen to remain silent on the accident details in court. Her shock soon turned to extreme anger when Lee decided not to let out what had happened.

Her husband, Mr. Tan, was 21 when he died after an accident outside Las Vegas KTV at Havelock Road. That night, he was discussing supper plans with a group of friends, which included Lee. Later, Mr. Tan was found unconscious on the ground, next to the car driven by Lee. Mr. Tan died in the hospital a few hours later. Due to drinking driving, Lee was fined $3,000 and banned from driving for two years last month.

Lee, Ms Lo and her husband were colleagues at Asia Pacific-Breweries(APB).

She only heard of the accident and her husband’s death the next morning after the accident as she had switched off her band-phone that night. She told The New Paper, “Receiving the call, I thought it was a joke. I thought he had got his friend to call me to ask me out.” Ms Lo had moved out to live alone for three weeks because of a disagreement with her husband. “The next time I saw him was at the mortuary.(太平间)” She said that Lee went to visit her some days ago but didn’t apologize to her. “He looked sorry but he didn’t speak to me. I wanted to forgive him, but now I have no chance to tell him.” she said.
