MoMo - the part of this that your friends missed was their nationality is irrelevant. Since they are listed as executive officers of a US publicly traded company...that brings all sorts of unwanted attention.
Somebody forget to account for that when they decided that the identities would be taken out of the story by killing them off.
Since those authorities are going to assume they are real...guess what...I can count 4 US government agencies that would be really interested. But they will soon discover that there were no deaths and that both identities were fabricated...but by that point too many rocks will have been turned over...and who knows what will be under those.
