why? Even though YUCHUN and Yu A In's hair and leg hair were positive for drugs...Lee Sun Kyun's ”identification is not possible”

YUCHUN (former JYJ) and actor Yu A In were also forced to undergo a detailed drug evaluation, and actor Lee Sun Kyun was found to be unable to be tested for drugs. Police once again investigated Lee Sun Kyun's leg hair.
We plan to take samples and secure evidence. According to the Incheon-gu Police Agency on the 15th, a detailed examination of the leg hair of Lee Sun Kyun, who is suspected of violating the drug control law, revealed that
It was determined that ``narcotics identification was not possible.'' On the 4th of this month, Lee Sun Kyun was summoned to the Incheon Police Agency's drug crime investigation department for the second time. During this process, the police collected leg hair and
A detailed examination was requested to the National Forensic Science Agency (see below). The National Institute of Forensic Sciences conveyed its opinion to the police, saying, ``There was not enough body hair (sampled) to make an identification.''

A reagent test was negative, but a detailed examination of his leg hair detected drug components. Furthermore, YUCHUN was sentenced to a suspended prison sentence.
Furthermore, in the case of Yu A In, the Food and Drug Safety Agency suspected that she was a habitual user of propofol.
I leaned back. Police launched an investigation and conducted hair and urine tests on Yu A In immediately after entering the country from the United States. His hair contained traces of propofol, marijuana, cocaine,
Even ketamine was detected, causing a stir. Furthermore, Yu A In's first trial will be held in December. On the other hand, unlike YUCHUN and Yu A In, Lee received a negative test result for drugs or an untestable test result.
It seems that the police investigation into Sung-gyun will be difficult. The police continue to be criticized for failing to secure drug evidence for Lee Sun Kyun and conducting an unreasonable investigation.
