SIBU, MALAYSIA: Convinced her husband was unfaithful to her, a 34-year-old homemaker killed their only child and took her own life on Sunday.

Hung Yu Yuen strangled her 6-year-old son David Ting Fu Soon, and then hanged herself from the ceiling fan in the sitting room.

She left a note written in Chinese characters, venting her frustration on her husband: "I've had enough and I will go together with my son. I can no longer live a lie."

Hung's 36-year-old husband, a car accessories salesman here, was not at home at the time of the tragedy.

A neighbour heard a woman's scream from the family's single-storey terrace house in Jalan Lang-sat at 7.40pm and notified the police, who arrived 10 minutes later.

The house was locked. After trying to reach Hung on the telephone several times, police broke in.

They found Hung hanging from the fan with a rope. David was lying nearby.

Both bodies also had slash wounds -- Hung on the right wrist and David on the left -- and police found a bloody meat cleaver.

David also had abrasions on the neck, believed to have been caused by strangulation with a rope, according to Sibu police chief Assistant Commissioner Shafie Ismail.

"This is a straightforward case," Shafie said yesterday. "We found no evidence of foul play and have classified the case as sudden death."

A statement was recorded from the husband and he was later released.

The couple had been married for more than six years.
