The 19-year-old, identified only by her surname Lin, was taken into custody in Miaoli County in the north-west of the island after she allegedly stabbed her uncle in the stomach with a 29-centimetre knife, according to the semi-official Central News Agency.
Based on their initial investigation, the police said the teen was connecting to the internet around 2 am when her uncle shut the power down. An argument ensued, and the teen pulled out the knife.
The 37-year-old uncle, whose name was not released, died of his wounds in a local hospital.
Lin’s grandmother, who also lived in the home, said the uncle had a bad temper, and would shut down the power of the house occasionally while Lin was surfing the web because he was annoyed that she stayed up so late.
A representative from Miaoli’s prosecutors office declined to comment on the case, but said a murder conviction in Taiwan carries a penalty ranging from 10 years in prison to a death sentence. (dpa/NAN)
