Drug cartels are at war with the Mexican government.
They have money to buy something like this.

Buy what? Employ scientists or buy the components to experiment(which Mexican narcogangsters can't)?

If this is man-made, it has to be from professional labs with first rate scientists in a country with the ressources and brainpower to do it (or rogue scientists in such a country).

It can hardly be from some podunk backwater country.
