==Biography==
===Sandbox Murder at Dawn Case===
Yamada and Hajime Satou come to the park to identify their friend Tatsuo Kinoshita's corpse and be questioned. Satou confirms that it is Kinoshita, and Yamada cannot believe that he is dead. When he and Satou introduce themselves to Totomaru Isshiki and Ron Kamonohashi, they immediately recognize Yamada's name from the writing in the sandbox—"I was killed by Tetsu Yamada"—, and Totomaru asks him about it. Yamada denies that he killed Kinoshita and says that buried corpses cannot write; someone must be framing him.
Ron then asks Yamada why his shoes are full of dirt and sand if he has only just arrived. Yamada replies that he has been in the mountains lately and that he has an alibi for the time of Kinoshita's death: He was at home from midnight to now, 7:20 a.m. He was watching a movie with friends and only just came out with Satou to take out the trash. Yamada asks Toto to quickly catch his best friend's murderer.
At 7:40 a.m., Totomaru and Ron gather Yamada, Satou, and the other police officers. Totomaru then tells them what happened: Yamada killed Kinoshita.
Before the movie started at 12 a.m., Yamada drugged Kinoshita to make him fall asleep before he dragged him to the nearby park. There, he dug a hole in the sandbox and buried Kinoshita in it, but left the space around his head free of sand. Yamada ran a hose through the sand to provide him with air and covered Kinoshita's head with a blue sheet and weighted the sheet down with four stones. In the middle of the sheet was a hole, and when Yamada placed sand on top of the sheet, it was turned into an antlion trap: The sand slowly fell through the hole and onto Kinoshita's head. The sand gradually covered his head, and Kinoshita died of asphyxiation at around 3 a.m.
Yamada had also tied a string to the sheet so that he could pull it away and to his house after Kinoshita was dead. Because of the time shift caused by the suffocation device and the fact that he could easily remove the sheet from his home, Yamada dared to write "I was killed by Tetsu Yamada" into the sand. If he did that, he would also get questioned early enough to ensure that his testimony would not fall apart.
Yamada confesses and says that his life is now over. He adds that he killed Kinoshita because he flirted with Mika with whom Yamada has been together since junior high school. His confession triggers Ron's Kill on Sight ability, and Ron pressures Yamada to stab himself. Dazed, Yamada takes an empty bottle from his trash bag and shatters it. Before he can stab himself with it, Toto stops him by tackling him to the ground. Yamada is arrested afterward.
