A rape and murder, plus two more sex attacks, have left Tuen Mun residents

EVERY night the Tuen Mun killer strikes anew; night after night stalking the housing estate's grim hallways; night after night raping, strangling, and murdering Ip Wing-sze . . . night after night returning to drive another stake into her mother's grieving heart.

''Every night, he comes in my sleep and kills her. Over and over and over again,'' said Ip Ng Kei-kit, with tears in her eyes.

''At 1 am, my heart starts pounding, boom, boom, boom. I feel him coming, grabbing her, and I see it all. I grab my head and try to scream, but can't.

''I just can't take it . . . he's killing me, too.'' One week after suffering a mother's worst nightmare - identifying the battered and bruised body of her teenage daughter - Mrs Ip opened her grieving heart to the Sunday Morning Post.

But it was Ip Keung-ki, father of the 19-year-old who was brutally raped and strangled during the early hours of last Sunday, who relived his eldest daughter's last moments.

''She had been out with friends, at a movie,'' he said. ''Afterwards, she called a taxi to come home. One of the boys offered to guide her home, to walk her to the door.'' Normally, she would have been with her boyfriend, who would have seen her safely home. But he had hurt his leg a few days earlier and on the fateful night wasn't with Wing-sze and her friends on their Saturday night outing.
