A 40-year-old Indonesian woman, who was seen in the early hours of Friday carrying a blood-covered knife, turned herself in at a police precinct in Changhua, Taiwan, after allegedly killing her 41-year-old former husband and 15-year-old daughter.

The incident happened in Puxin at about 1 am when the woman was having a heated discussion with her former husband about work after earlier arguing about their 15-year-old daughter, the Liberty Times reported.

As the argument heated up, the woman grabbed a fruit knife – which she had bought a week earlier and secretly stored in the bedroom – and stabbed the man in the neck and abdomen 14 times.

The woman, who had fallen out with her 15-year-old daughter who was close to her father, then stabbed her sleeping daughter more than 10 times. The daughter was pronounced dead at the scene, while the man was later pronounced dead at the Ministry of Health and Welfare Hospital in Changhua.

A preliminary police investigation found that the woman, who had married and divorced three times, had been living with the family due to financial difficulties.
