10 Unsolved Crimes

It is always odd to me that governments find masterminds and serial killers all the time, whether they have changed their identities or are found in spider holes. Yet, when it comes to certain crimes it is almost as if those in charge “give up”. These 10 crimes lack the evidence or the interest to be solved. Honestly, I believe 8 out of 10 are cover-ups. I mean, really dude, of all the world’s resources we can’t figure these 10 unsolved crimes out?
