Hans Smits told Fox News he spent 10 years hiding a whistleblower who said he escaped a criminal "posse" headed by Poste. The man, who The Case Breakers only referred to as Wil, told Smits the posse roamed California's High Sierra region and that he was "groomed into a killing machine."
In addition, Wil said he witnessed Poste burying murder weapons in the woods, Smits said.
"They put out several bear caches out there in case something happened," Smits said.
Smits said he gave Wil financial, logistical and emotional support over the years and moved him around for nearly 10 years in an effort to keep him safe.
"I'm the one that took him to the FBI office and put him on a train and sent him out of state," Smits said.
Another woman named Michelle said she was common-law married to Poste's son. She told Fox News she was a victim of harassment by Poste and his "posse" during the relationship that included damaging her car and other incidents.
Despite being dead for three years, some people are mysteriously still loyal to him, said Michelle, who also declined to provide her last name.
"He targeted young men who didn't have a father figure," she said. "It was a posse of three but the one [Poste] did a lot of damage. He still has some kind of control… and he's gone."
