"Meanwhile, from the results of witness examinations and evidence at the location, the police found a confession in a diary. In the notes, the victim intended to withdraw due to conflicts with their seniors. "We check the evidence of the diary, that he felt the burden of his lessons and his seniors," he said."

"The victim was found dead after suspicions arose because the victim had not been contacted since morning by her boyfriend. When they visited the boarding room, it was locked from the inside. They then tried to call her phone, but there was no answer. 'We asked her friend for help; her friend checked the boarding house in Tembalang, and it was empty,' he said."
