Overview
- Ichihara police said the high school student allegedly chopped oleander leaves into miso soup at their home around midday on July 17.
- Forensic testing detected a lethal level of the toxin oleandrin in the leaves mixed into the soup.
- The uncle spat out the soup after noticing an odd taste, later reported numbness and abdominal pain, and was treated at a hospital with minor injuries.
- The student has admitted the allegation, telling investigators he decided to kill because he could not tolerate the snoring.
- He was arrested that evening for striking two women with a hammer at JR Chiba Station and sent to family court, which canceled his custodial measure on September 1 as police now probe links between the cases and how he obtained the plant.
