It is difficult to believe these "stories". Can anyone be so dumb to actually hire a murderer for just $5,000? I still remember the case of Ross William Ulbricht. The FBI wanted to make sure that he remains behind bars for the rest of his life and it is being alleged that they created some fake web chats showing that he hired contract killers to take down his competitors. It is very easy to create fake web chats.
So you believe Ross didn't put a hit to those men?
The guy looks very harmless actually but later it was discovered that the wallet where he sent the fee for the hit was his old friend who also tried to scam him for this hits. There really isn't a way to know all the facts besides those FBI men.
One shouldn't trust a hired hitman because ultimately these men are just going to extort you in the end. Lots of stories about this.
