Two women in their early 20s were found dead inside a car after they apparently gassed themselves in Japan's latest suicide pact, police said Thursday.
Investigators discovered two empty bottles that contained a bathwater additive and detergent, leading them to suspect that the two mixed the two liquids to generate toxic hydrogen sulfide gas.
The two elementary school classmates were identified as 21- and 22-year-old women from Namegawa, Saitama Prefecture.
