Dangerous Japanese 'Detergent Suicide' Technique Creeps Into U.S. www.wired.com

A suicide technique that mixes household chemicals to produce a deadly hydrogen sulfide gas became a grisly fad in Japan last year.
Now it's slowly seeping into the United States over the internet, according to emergency workers, who are alarmed at the potential for innocent causalities.
Then in December, emergency workers responding to a call at Lake Allatoona in Bartow County, Georgia, found a similar scene.
Nobody connected the cases until last month, when a Texas surgeon realized that a new and dangerous suicide method was making the rounds.
Dr. Paul Pepe, chief of emergency medicine at UT Southwestern Medical Center, warned emergency workers that they could become innocent casualties of the technique if they're not careful.
