<p> A woman who knows the Adachi family told FRIDAY Digital, &#8220;The Adachi family is a family that has been in the spotlight all over Japan. The family was involved in a case that caught the attention of all of Japan. The family&#8217;s true circumstances are gradually coming to light.</p>
<p> On April 16, the Kyoto Prefectural Police arrested Yuki Adachi, 37, the adoptive father of Yuki and a company employee, on suspicion of abandoning the body of Yuki&#8217;s sixth grader, Yuki Adachi, who was found dead in a mountain in Sonobe-cho, Nantan City, Kyoto Prefecture.</p>
<p><span class="strongInContent"> The suspect admitted to the interrogation that &#8220;there is no doubt that I did it,&#8221; and also made a statement to the effect that &#8220;I strangled him to death.</span></p>
<p><span class="strongInContent"> On April 18, police began forensic work in a public restroom near the suspect&#8217;s home. It is believed that the suspect may have temporarily abandoned Yuki&#8217;s body in this toilet. The prefectural police are continuing their investigation, believing that the suspect had moved Yuki&#8217;s body from one place to another in addition to the forest where Yuki&#8217;s body was found.</span></p>

<p> When a reporter from FRIDAY Digital visited the area, the flower stand was overflowing with bouquets of flowers, sweets, and other offerings. Even before sunset, many people were still mourning Yuki&#8217;s death.</p>

<h2> Relatives are unable to leave the house.</h2>
<p> Four generations lived together in the home where the suspect lived: Yuki, his mother, grandmother, and great-grandmother. Yuki&#8217;s mother married the suspect&#8217;s son-in-law.</p>
<div data-friday-ad-slot="AD_inArticle"></div>
<p><span class="strongInContent"> Yūki-kun&#8217;s mother used to work at a beauty salon in Tokyo, and during that time she married another man, Yūki. She gave birth to Yuki. However, they divorced when Yuki turned one year old, and moved back to Nantan City, Kyoto Prefecture. She then remarried the suspect, Yuuki, whom she is said to have met at work.</span></p>
<p> Yūki is said to have been loved by the Adachi family as <span class="strongInContent">a &#8220;solid child.</span> On the other hand, there were various opinions about his mother&#8217;s marriage. A woman who knows the Adachi family said, &#8220;Yūki&#8217;s mother moved to Tokyo to live with her husband.</p>
<p><span class="strongInContent"> When Yuki&#8217;s mother got married in Tokyo, I heard that not all the relatives were in favor of the marriage. Perhaps because of this, the mother did not consult with them about the marriage beforehand. Her family was also introduced to her out of the blue, and she seemed a little confused. When she remarried, the suspect entered the Adachi family as an adopted son-in-law in response to the relatives&#8217; offer, &#8216;Don&#8217;t change the Adachi name only.'&#8221;</span></p>
<p> The relatives of the Adachi family are now said to be exhausted, both physically and mentally. The woman mentioned above continues, &#8220;My great-grandmother and grandmother live in the same house.</p>
<p><span class="strongInContent"> The Adachi family&#8217;s home, where my great-grandmother and grandmother live, is visited daily by the media and investigators. The relatives are so mentally exhausted that they cannot even leave the house. All the relatives except for the suspect, Yuuki, are victims. So why should they be hunted down &#8230;&#8230;&#8221;</span></p>
<p> The wishes of the relatives, who accepted the suspect Yuuki on the condition that he would be their son-in-law, have been betrayed in the worst possible way.</p>
