The Nagasaki Family Court on Thursday extended for another year the detention with limited freedom of a 14-year-old boy who murdered a 4-year-old boy in Nagasaki in July 2003.

The court's ruling follows a Nagasaki child consultation center's recommendation that the teen's detention under lock and key at a independent-living facility be extended as he had not yet reflected deeply on his crimes.

The teen, whose name is being withheld because he is a minor, killed the boy on July 1, 2003, by pushing him off the roof of an eight-story parking structure, after abducting and molesting him.

He was sent to a facility in the city of Saitama in September 2003, and last September his detention was extended by a year. A one-year extension, decided during a closed-door juvenile proceeding, in this type of case is unusual.
