KANCHANABURI - A 13-year-old girl killed her young stepsister in a fight over use of a mobile phone, and her teenage uncle had helped conceal the victim’s body over the past week, according to police investigators.

Pol Lt Gen Pisit Tanprasert, chief of Provincial Police Region 7, said the 13-year-old suffocated her 7-year-old stepsister at their house in Ban Thi Khrong in tambon Prang Play of Sangkhla Buri district on the afternoon of May 30.

The two girls had the same mother, but different fathers. The mother told police the two girls had quarrelled a lot, and often fought over the use of the mobile phone.

The dead girl's body was initially hidden in a wardrobe. On the evening of May 30, the mother's 17-year-old younger brother took the body to a rubber plantation about 600 metres from the house and left it there. A sack used to carry the body was burnt nearby.

Pol Lt Gen Pisit said the mother was left in shock by the investigators' revelations. The 13-year-old girl and her 17-year-old uncle had been tight-lipped about the stepsister's disappearance.

Mental healthcare staff would counsel the distraught mother, he said.

The 7-year-old's body was found on June 1. According to earlier reports, an initial examination found signs of sexual assault on the body.

The two minors are the prime suspects. The police investigation was continuing.
