The latest information regarding the death of Ms. Kim which stated that a pseudomonas infection was the main cause, has also stirred up controversy. After news of the pseudomonas infection, the Choi family submitted official documentation to police that pseudomonas was not discovered from Bugsy during a recent checkup. However, in response, Ms. Kim's side argued the likelihood that the Choi's may have washed Bugsy after the biting incident, and that it will be difficult to determine if the harmful bacteria was present in Bugsy during the biting. Despite the argument, Ms. Kim's side maintained their position not to take any legal measures against the Choi's. 

The hospital's side also defended against the possibility of a secondary infection acquired during treatment, claiming that Ms. Kim received both a disinfection and a vaccine during her visit, which lasted no longer than an hour.
