A man already detained in connection with the March slaying of a 9-year-old Vietnamese girl in Chiba Prefecture will be served a new warrant on Friday charging him with murder, according to investigative sources.

Yasumasa Shibuya, 46, was arrested last month on suspicion of abandoning the body of Le Thi Nhat Linh in Abiko, Chiba, after she disappeared on her way to school in Matsudo, also in the prefecture, on the morning of March 24. Shibuya was the head of a parents' association at Linh's elementary school.

The sources said the murder charge is based on a DNA sample linked to Shibuya taken from Linh's body, as well as DNA taken from one of her hairs discovered in the back seat of Shibuya's car.
