the 18th, at an office in Seocho-gu, Seoul, two employees drank water from a bottled water and collapsed.
Suspect Kang Mo, a colleague of the victims' company, made an extreme choice at home after truancy.
The police booked and investigated the deceased on charges of special injury, but decided to change the charge to murder.
This is because one male employee among the fallen victims died the day before (23rd).
Sodium azide, used as an insecticide, was detected in the blood of Kang and the deceased, and the police confirmed that Kang purchased this substance through an internet shopping mall last month.
Sodium azide, a hazardous chemical, can only be purchased through registration with the affiliated institution at the place of purchase.
With the cause of the death revealed to some extent, the police are focusing their investigations to determine the motive for the crime.
It is known that a company employee stated that Mr. Kang may have been dissatisfied with the possibility of being sent to a province.
However, as Kang did not leave a will, the police are concentrating on cell phone forensics and investigations to find the direct motive for the crime.
