Suspicion is mounting that a Kyoto Prefecture woman under arrest for allegedly killing her husband may have also killed previous spouses and lovers.
Chisako Kakehi, 67, was arrested Wednesday on suspicion of murdering Isao Kakehi, 75, who died last December in his home in Muko, Kyoto Prefecture. The Kyoto Prefectural Police found traces of cyanide in his body.
Investigators said they also detected a trace of cyanide in personal belongings that Chisako Kakehi disposed of, and suspect she used the poisonous substance to kill her husband. They are searching to determine how she obtained the cyanide.
