The president of Schindler Elevator K.K. offered a silent prayer Wednesday at the site in Tokyo where a teenage boy was killed when one of the company's elevators malfunctioned exactly three years ago.

Holding a bouquet of white flowers, John Bundy of the Japan unit of Swiss elevator maker Schindler Holding Ltd., crossed himself, bowed and said he was thinking about the teen's family and praying sincerely for the victim.

On June 3, 2006, 16-year-old Hirosuke Ichikawa, a high school student, was crushed to death between a Schindler elevator and the floor frame of the housing complex in which he lived in Minato Ward as the elevator suddenly ascended with its doors open.

Six people are under criminal investigation over the incident, including two Schindler Elevator employees.
