A woman's attempt to fulfil her father's dying wish not to waste four packets of heroin landed her in jail yesterday. Canteen operator Ng Lai-ip, 37, was jailed for 2.5 years for possessing the 12.99 grams for the purpose of trafficking. She was convicted after pleading not guilty at the District Court. 'I accept that the defendant did not want to go against the wishes of her late father, she did not want to waste the drug,' Deputy District Judge Peter Law Tak-chuen said. The mother of a 16-year-old son hid the packets in a Kwai Chung factory canteen. Police searched the premises on February 8 and found two of the packets. Ng admitted the substance was heroin and led the police officers to the other packets. She said the drug was left to her by her father, who had died in December 1998. It was not explained in court how her father had come to have the heroin. He had instructed Ng to sell the heroin and she intended to do so at a price of $1,000 per packet. Deputy Judge Law noted the total estimated market value of the four packets of heroin was about $7,000. He accepted that Ng did not make a living out of selling drugs.
