(CNA Reporter Tai Ya-chen, Tokyo, 16th) In the case of the death of an 11-year-old boy in Nantan City, Kyoto Prefecture, Japan, the 37-year-old stepfather, Yuki Adachi, confessed to murdering the boy and dumping his body alone. Through interviews with neighbors and citizens, Japanese media gradually pieced together the boy's family situation and the stepfather's character. One shop owner recalled that when he came to the store to distribute missing person flyers, he was expressionless and silent, making people feel very unnatural.
Japanese police announced the establishment of a special investigation headquarters led by the chief of the criminal investigation division this morning. The police stated that they have confirmed the boy was still alive on the morning of March 23, the day he went missing. Yuki Adachi has confessed that he alone was responsible for dumping the body. Police continue to clarify the motive and the boy's cause of death.
According to reports by the Yomiuri Shimbun, a male shop owner in his 60s in Nantan City stated that in late March, a man suspected to be Yuki Adachi came to his store with a female relative to ask if they had seen the boy.
He recalled that the woman looked anxious and handed over flyers appealing for clues, while the man remained expressionless and silent. He stated, "It felt very unnatural."
According to reports from the Sankei Shimbun and NEWS Post Seven, on the day the boy went missing, Yuki Adachi proactively reported to the police, claiming he had dropped the boy off at school. It is understood that he remarried the boy's mother last year and lived with them, marrying into the family and changing his surname to Adachi. However, among nearby residents, many said they "had never seen him."
A neighbor pointed out that the boy was an only child, originally living with his mother and grandmother. The impression given was of a "very harmonious family relationship," and the mother and son were occasionally seen taking walks together. But the neighbor said: "I never saw the father, and I don't know what kind of person he is."
Another neighbor who had contact with the Adachi family before the boy was born said, "Neighborhood interactions here are very close; we even casually enter each other's homes. But Mother Adachi might be more modern and doesn't seem very adept at this kind of socializing. She remarried after returning here, but Grandmother Adachi was reluctant to talk about the remarriage. I only heard the man was from her workplace. My grandfather and I actually almost never saw him."
"Shukan Bunshun" disclosed that the boy's mother and the suspect met at an electrical machinery manufacturing plant. The boy's mother originally worked as a beautician in Tokyo, got divorced after marrying and having a child, and then returned to her hometown in Nantan City.
On the other hand, after graduating from high school in Kyoto City, the suspect joined the factory as a full-time employee. It is said that he had a diligent work attitude, gradually earned promotions, and was recently promoted to quality control section chief. He was good with computers and had a decent reputation among his superiors.
A colleague said, "Perhaps because his wife used to be a beautician, he recently permed his hair into curls and wore black-framed glasses; at first glance, he looked a bit like a computer nerd. Because he's not tall, I remember he always wore platform shoes."
His marriage to the boy's mother went through some twists and turns. Colleagues revealed that he was previously married to a woman from the same factory who was 16 years his senior, and they had a child who is about 10 years old this year. Even so, he fell for the boy's mother, who was a single mother. During breaks, the two were always being affectionate in the break room. Later, the company transferred the boy's mother to another department because of this.
However, the two did not break up. Colleagues said the suspect divorced his wife who was 16 years older and remarried the boy's mother in December last year.
Colleagues noted that ever since he started dating the boy's mother, he frequently took time off work and often wore a preoccupied expression. "We were actually always worried about him."
Reportedly, the suspect's elementary and junior high school classmates said he often summarized everyone's opinions and played the role of final coordinator. He was even the student council president in junior high. He had a mild personality and was very filial to his grandparents.
However, a classmate revealed that around the fifth or sixth grade, he once suddenly yelled, "You bastard!" and smashed a desk against the wall. It seemed a classmate had said something about his grandmother or family, perhaps going too far, which enraged him.
The classmate said, "He didn't slowly accumulate anger; it just suddenly exploded. Precisely because he was usually very mild-mannered, this incident left a particularly deep impression." (Editor: Tien Jui-hua) 1150416
