It is known that no poison was detected in the bottled water collected from the site in connection with the recent case of poisoning from a bottled water at a company in Yangjae-dong, Seocho-gu.



According to the police today (22nd), the National Forensic Research Institute made the first opinion that no poison was found in the bottle of water at the scene.



In this regard, it is known that the police believe that the bottled water analyzed by the National Forensic Service may not contain the water that the male and female employees who were the victims drank.



A police official explained, "The report was made 7 hours after the incident, and the site was not preserved. So, it is estimated that he drank (water containing poison)."



Police are also considering the possibility that the water bottle may have been replaced or thrown away in the seven-hour period.



Kang Mo, an employee of the company, who was found dead at home on the 19th, the day after the incident, was arrested by the police as a suspect in the incident.



Because his real residence was different from the home address he gave to the company, the police found his home by signal and interrogation from the base station.



When the police arrived at the house, Kang was found dead after drinking poison.



There were traces of fingerprint identification at the house, and it is said that traces of finding papers related to certain poisons with a cell phone were also found along with several poisons.



It is known that the mobile phone forensics was over, but the part that could be seen as the motive for the crime was not identified.



Police also applied for a warrant to track the account.



Co-workers stated that there was no bullying in the workplace during the police investigation, but the police are investigating the possibility of internal conflicts in mind.



On the other hand, the police believe that the suspect is the same person in relation to the fact that Mr. A and Mr. Kang, an employee of the same company who suffered similar damage two weeks before the incident, were roommates in the company house for about a year.



The police found that the ingredients detected in the drink that A drank at the time were the same as the poisonous ingredients found in Kang's house.



Since there were other employees besides Kang and A living in the house, the police are investigating with various possibilities open.
