On March 16th, the National Forensic Service released an official statement confirming that Jang Ja Yeon’s letters were fabricated.
At 10:00 AM KST, the chief of the NFS, Yang Hoo Yeol, opened an official briefing with the media and reported, “After comparing Jang Ja Yeon’s original handwriting to Jun’s handwriting and the letters in question, results have shown that the letters are not in line with Jang Ja Yeon’s original handwriting. Many of grammatical errors are in line with the mistakes Jun made in his personal letters, so we believe that Jang Ja Yeon’s letters were fabricated by Jun.”
He concluded, “The letters that Jun claimed were sent to him by Jang Ja Yeon have a completely different handwriting style to Jang Ja Yeon’s original handwriting. Jang Ja Yeon did not write these letters.”
When asked about fingerprint identification, the NFS responded, “That is not our job, it is up to the police.”
