As is the style in Korea, photographers were quite close (1, 2, 3) to capture all the grief on film:
"Funeral porn" is the indelicate name given to these types of photographs that fill the online news sites each time there's a newsworthy funeral, and demonstrate the importance placed on public displays of emotion and mourning. Yonhap has a two-minute video from the funeral home.
His name is released in the latest articles, and is written on the banner above, and in a comment on the 27th "Pakou" wrote:
I'm super sad. The kid that was killed was a very nice guy. We taught English together this summer in Gokseong. My prayers to his family.
After the murder Gwangju National University of Education said it was halting its exchange programs with Russia; from KBS:
Gwangju National University of Education has decided to suspend its exchange programs with Russia after one of its students was killed by a group of Russian youths last week.
The university said Monday that it decided to suspend its program with Altai State University in Barnaul, Russia, in the wake of the recent incident, adding that it is also carefully reviewing whether to carry out Gwangju’s other overseas exchange programs that are usually conducted during vacation periods.
There is certainly plenty of reason to think the attack was racially motivated, and other articles have said Kang wasn't the first Korean student to be killed in Russia.
