Once it starts, it becomes a trend. People get the idea. Or if you beleive in ghosts & spirits, it's the dead spirit of the previous suicide cases calling.

Like 9 storey flats in Melaka, many suicides there till MPM lock door to roof area. Then those ppl go jump from the higher floors of the flats. Nearby got tall2 hotels they dont go

Got talk modern what, first line, once start, people get the idea. They read/hear got ppl suicide at X place, if they depressed, they also start to think of jumping from there. Siap give other example also
