The reason why journalists already mentioned this on broadcasts back in 2016

Around October 2016, when signs of President Park Geun-hye's impeachment were appearing, citizens took to the streets, right? Journalists probably covered it on broadcast.
At that time, some female journalists even mentioned this person's name during a live broadcast, saying, "We must save that child in Busan." They likely reported it while covering the protests on the streets.
That was right around the time this person became a schizophrenic patient after failing an interview in December 2015.
That person is now mentioning the Busan incident through "refreshing" (cider-like) remarks.
The case is not over yet.
