Chris Tarbell states that there are logs about 6 imaginary "murder of hire"'s .. none of which actually took place, two were faked by the FBI(?) and four were scams run by third parties outside the USA.
In the absence of any other context it's assumed these were acts of "intent to murder" but that's about it .. logs that look like a duck and probably were a duck.
But no actual murders that anyone could find, no bodies, etc.
