Police offer Y3 million reward for killer of Setagaya family of four

Police on Friday offered a 3 million yen reward for information leading to the arrest of the killer of a family of four in Setagaya. On Dec 31, 2000, Mikio Miyazawa, 44, his wife Yasuko, 41, daughter Niina, 8, and son Rei, 6, were stabbed to death in their home.
Tokyo Metropolitan Police investigators remain stumped, despite fingerprints left by the perpetrator and a wealth of other forensic evidence at the crime scene, as the killer apparently lingered in the house for several hours after committing the grisly crimes, eating ice cream and surfing the web on his victim's personal computer.
