The main suspect in the slaying of a 9-year-old Vietnamese girl in Chiba Prefecture in March was served a fresh arrest warrant for murder on Friday.
The suspect, Yasumasa Shibuya, 46, has refused to speak to investigators. He was arrested last month on suspicion of abandoning the body of Le Thi Nhat Linh near a drainage ditch in Abiko, Chiba Prefecture, according to the prefectural police.
A DNA sample from the victim's body matched Shibuya's DNA and hair found in the suspect's car matched the victim's DNA, investigation sources said.
