The Southern Province Hospital was relieved by the results of the police's latest investigation. The nurse in charge of prescribing the medication was absent-minded when she went to work that day due to family reasons. She also mistook the dosage of the medication. In addition, the nurse in charge of verification received a call midway and did not check it carefully again. That was how the wrong dosage was administered.
In other words, the result of the police's investigation showed that it was a work error and not a crime.
The military did not immediately agree with the results of the police investigation. Instead, they investigated more carefully and thoroughly. They combed through the entire hospital's network of relationships. They even investigated the family background of the cleaner who was in charge of cleaning Principal Chen's ward.
