What would u do if 2 ppl u don't know told u they're commuting suicide? *based on real events* ?

So Hailie and Riley are planning a mass suicide. At 3:15 am, April 3, hailies gonna eat cyanide and rileys gonna slit his wrists. Of course hailie dies first in 10 min and rileys stuck waiting. He texts on facebook, myspace and twitter that he's gonna die and his wrists are alredy slit.He also tells them that hailies alredy dead next to him and he's waitin to bleed out. He also told eeryone who wants to die to join him. One guy says he will tomorrow via iron pills and another girl says she will tomorrow via brakefluid on her birthday to show how she regret being born. None of his Internet friends know him personally however he does leave his phone number behind. Riley is a jackass and called all the girls ugly andfat and dissed all the guys. Everyone hates him. He sends a pcture of his bloody wrist to them. 15 ppl see this pic and know what's going on. How many ppl will call the cops and what do u think the cops would do? What would u do?Based on real events. Actually they are real events. Serious answers please
