IPOH, MALAYSIA: Worried for his teenage sister who had been missing for several days, a salesman went twice to her boyfriend's house in Kampung Kuala Kuang, Chemor, hoping to get some news of her.

While the first visit was fruitless, the second, at 3am, led to the discovery of Yee Wei Qing, 17, stuffed inside the boot of a car parked in the porch of her boyfriend's house.

Si Van, 35, told reporters he had first gone to the house at 6pm on Tuesday but only learnt that his sister had left her wallet and mobile phone behind.

He then went to the police station to lodge a missing person's report.

When he returned close to midnight, accompanied by policemen, he said they realised that the boyfriend's father had locked himself inside his bedroom.

"Every time we asked him to open the door, he told us not to disturb him saying he wanted to sleep," Si Van claimed when met at the Ipoh Hospital mortuary yesterday.

"When we broke in, we saw what looked like bloodstains on the floor. The father also tried to keep us from the bed but we found her shoes covered with newspaper."

Their search then extended to the father's Nissan Sunny car where Si Van saw what looked like a white sack inside the boot. The policemen then stopped him and called for the forensics team.

Perak police chief Deputy Comm Datuk Zulkifli Abdullah said Wei Qing, who had head injuries, was found fully dressed.

A search of the scene revealed bloodstains and a piece of wood that might have been used as a murder weapon, he told reporters at a police function yesterday.

Wei Qing's grief-stricken mother told reporters that the boyfriend was a "shy" sort and that her daughter had been going out with him for about a year.

She said Wei Qing used to stay over at her boyfriend's house nearby, and had not been home to Kampung Tawas for about a week.

The family only started getting worried after they received a letter from the school stating that Wei Qing had been playing truant from school "on and off" for a month.

Later yesterday, Acting Ipoh OCPD Supt Ibrahim Abu Bakar said Wei Qing, a Form Four student, had not been sexually abused.

"The post-mortem showed that she died of excessive blood loss from her head injuries," he said, adding that her hands were bruised as if she had tried to ward off an attack.

The 18-year-old boyfriend and his father, who is in his 50s, have been remanded for seven days.
