Dangerous Japanese 'Detergent Suicide' Technique Creeps Into U.S.

At least 500 Japanese men, women and children took their lives in the first half of 2008 by following instructions posted on Japanese websites, which describe how to mix bath sulfur with toilet bowl cleaner to create a poisonous gas. One site includes an application to calculate the correct portions of each ingredient based on room volume, along with a PDF download of a ready-made warning sign to alert neighbors and emergency workers to the deadly hazard.
