TOKYO, Japan (AP) -- A 14-year-old Japanese girl killed herself by mixing laundry detergent with cleanser, releasing fumes that also sickened 90 people in her apartment house, police said Thursday as they grappled with a spate of similar suicides.


Emergency responders enter an apartment building in Konan, Japan, where a girl commited suicide.

None of the sickened neighbors in Konan, southern Japan, were severely ill, although about 10 were hospitalized, authorities said. The deadly hydrogen sulfide gas escaped from the girl's bathroom window and entered neighboring apartments.

The girl's suicide Wednesday night was part of an expanding string of similar deaths that experts say have been encouraged by Internet suicide sites since last summer.
