After suffering from a heart attack, McAfee eventually managed to successfully return to the U.S., where he ended his relationship with Herrera and married a former prostitute in Miami. Guerra, McAfee's lawyer, died a year after representing him.
In an interview with Esquire, the film's director Charlie Russell said he was unsure what to think about Herrera's claims that McAfee was still alive.

“I don’t know what I think and I don’t think she does,” Russell said during the interview. “She says it, then she looks at the camera, and I can’t work out whether she thinks it’s real or not. She’s someone who was very angry at John."
“He promised them a life together and I think they were genuinely in love, despite the huge age difference, I think he offered her a real different future, then he literally ditched her at the border and I think that’s very painful for her and it’s taken her years to get over that," Russell continued.
Prior to his death, McAfee had tweeted that if he was found dead in his jail cell, it wouldn't be as a result of suicide. Ultimately, Herrera's claims are the only evidence we have that the former software engineer is still alive.
