NAGOYA - Around 6:30 a.m. on May 14, a detective was walking through Kanayama Station in Nagoya, central Japan, on his way to work. As one of the city's major transportation hubs, it is bustling with people from early in the morning.

Suddenly he spotted a face in the crowd that resembled a person who had long been a thorn in the side of the Handa police department.
