On October 31, residents of Seoul were joyfully enjoying the festivities of Halloween

when they heard reports of a stampede in nearby Incheon 

The stampede apparently occurred when people attraction to see thecostume parade ran into too much competition

The death toll has now risen to 146, and more than 1,000 people are injured

The tragedy is still being investigated, but it is clear that the celebrations led to an excessive amount of crush

It is suspected that some costumes were not properly made- causing them to be too tight for the participants

This resulted in high numbers of injuries and fatalities

It is also possible that some costumes were not dyeable enough

which could have caused further injury if clothes catch on fire or became caught on straws
