A gun fanatic's 'obsession' with a fellow nurse yesterday ended in a nine-year jail term. Milky Lau Tat-keung, 25, was found guilty last month of shooting his love rival in the face after failing to win the young woman's heart with gifts. 'The shooting could well have been fatal,' Deputy Judge Colin Jackson said before passing the sentence in the Court of First Instance. Lau was a gun club member, and a cache of illegal weapons was discovered in his home and safe deposit box. The judge described the arsenal as 'deeply disturbing'. He said Lau had displayed 'a degree of obsession for the lady in question' by buying her a mobile phone and secretly programming it to divert all her calls to him. Lau, a trainee nurse, had showered Diane Ng Man-wai, 23, with gifts, promised her a monthly allowance and deposited $3,000 into her bank account. But this failed to win her away from long-term boyfriend Lo Fong-ping, 26. On November 18 last year, Lau waited outside Mr Lo's flat armed with a stun gun and a handgun. When Mr Lo emerged, Lau shot him in the face. The bullet pierced Mr Lo's cheek and exited through his neck without causing serious damage. Lau was convicted of shooting with intent and possession of arms and ammunition without a licence. The jury found him not guilty of possession of arms at the time of committing an offence.
