It has been confirmed that sodium azide, a toxic chemical, was detected in the blood of a suspect who died in the so-called 'water bottle poison incident' that occurred at a company in Seocho-gu, Seoul.
It is the same ingredient that was detected in the body of a victim who drank water from a bottle of water and fell into a serious condition and eventually died on the 23rd.
As a result of SBS coverage, sodium azide was found in the blood of a 35-year-old man named Kang Mo, who was found dead at his home at the autopsy of the National Institute of Forensic Sciences.
As sodium azide was detected in the body of the deceased, the same substance was detected as a result of a targeted test for the poison on Mr. Kang.
It is reported that the National Forensic Service is conducting additional blood tests for methanol and sodium hydroxide found together with sodium azide at Kang's house.
The Seocho Police Station in Seoul changed the charge against Kang from special injury to murder when the team leader in his 40s, who was Kang's boss, drank water from a bottle of water and collapsed and eventually died.
Kang was found dead after making an extreme choice at his home after the incident, and as a result of the police investigation, it was investigated that he had purchased sodium azide on the Internet.
Usually, when the suspect dies, the case is closed with 'no right to prosecute', but the police launched a forced investigation to determine the circumstances of the incident and charged Kang.
