Yes let's do the math. I agree it is going to take a team to kidnap a person and then hold them until the ransom is paid. It is going to take someone who can break into a home, transport the victim out of the home, into a secure, secret location. The victim must be fed, housed, taken care of to the extent they remain alive. And it all must be done in a way that the victim cannot see or detect the location and identify of the perpetrators. This will require at least two people. Perhaps more?I think it's too hard to hold hostages and it takes an enterprise. Also, kidnap and murder? in the U.S. means a possible death sentence.
Then they will need a person who has expertise in internet security and finance. Who can conduct the ransom part of the operation. This is a third person.
So a bare minimum of three people, perhaps more. In the Guthrie case they are asking for $6 million. It would have to be split at least three ways after operating expenses. $2 million might seem like a lot of money, but the people are facing the death penalty or life in prison. And will be on the lam or lookout for the rest of their lives. And they know that anyone in the rest of the team could turn them in at anytime to save their own skin.
