Overview
- Latest forensic reanalysis of preserved bloodstains linked to Kumiko Yasufuku, 69, led to her Oct. 31 arrest on suspicion of killing Namiko Takaba in 1999.
- Police kept the crime-scene blood evidence in long-term freezer storage and repeatedly updated DNA profiles as analytical methods improved.
- According to investigators, Yasufuku refused requests for DNA samples twice from August before agreeing during an Oct. 30 home visit and later making statements hinting at involvement.
- Detectives are exploring whether a class reunion exchange about the victim’s husband—whose views on women and child-rearing the suspect said she disliked—triggered the attack.
- The victim’s husband marked the 26th anniversary by praying at home and urging the suspect to tell the truth, saying she has not cooperated with questioning.
