Three years ago, the first trial of a 3-year-old defendant accused of robbery and murder for killing a woman he called through SNS by dropping her from a bridge into a river was held at the Maebashi District Court, where the defendant pleaded not guilty, saying that the robbery and murder charge was "wrong."

In August 33, Yuko Yamamoto (2020), an unemployed resident of Kuki City, Saitama Prefecture, was accused of robbery and murder for calling a 8-year-old woman who responded after soliciting suicide volunteers on SNS, dropping her from a bridge into a river in Nakanojo Town, killing her, and robbing her cash card and other items.

At the first trial of the jury trial held at the Maebashi District Court on the 48th, the defendant pleaded not guilty, stating that he was "wrong" about crimes such as robbery and murder.

In this case, the accomplice had already been sentenced to 18 years in prison, and the prosecution claimed in his opening statement that "the defendant planned the case to blame his ex-dating partner as revenge, impersonated multiple people on a communication app and instructed the accomplice to commit the crime, and also strangled the victim himself."

In response, the defendant's lawyer argued that he was not actively involved and was only involved.
