The attorney for an Arizona city where 19 firefighters died  while battling a massive woodland blaze says he was told it was an order from the group's supervisor led to their deaths in June 2013. Prescott City Attorney Jon Paladini claims the fire's sole survivor, lookout Brendan McDonough, heard the leader of the Granite Mountain Hotshots order the crew to leave a safe spot where the fire had already burned. Paladini tells the Arizona Republic that he was told the order came just before winds whipped Yarnell Hill into a deadly, all encompassing firestorm. Fatal orders? The Yarnell Hill Fire killed 19 firefighters in 2013, the worst disaster of its kind since 1933. New revelations now claim their deaths came after their supervisor gave orders for the crew to leave a safe zone . But first, Paladini claims McDonough heard crew supervisor Eric Marsh and his top deputy arguing over making the dangerous move. Marsh ordered it, Paladini says, while his deputy Jesse Steed warned against it. Whether or not Paladini's claim is true, neither man is alive to verify it. What's more, Paladini's claim is based on what he says he was told by Darrell Willis, former chief of woodland fires for the city. Paladini says McDonough told Willis about the deadly decision. But neither Willis nor McDonough will verify that account. McDonough told the Arizona Republic when asked about the radio interaction he allegedly heard between Marsh and Steed: 'I think you're being misinformed.' Prescott, Arizona City Attorney Jon Paladini (left) claims that the lone surviving Granite Mountain Hotshot Brendan McDonough overheard an argument between the crew leader and his deputy over the move, which would prove deadly . Former Prescott Fire Division Chief Darrell Willis, seen here speaking during a memorial service honoring the 19 fallen firefighters, says McDonough came to him to get something 'off his shoulders.' Willis won't say what that was, but both he and McDonough have denied it was a recounting of any argument between crew chief Eric Marsh and his deputy Jesse Steed . And when the paper asked Willis about the argument, Willis said: 'That was not part of the detail that I knew — that he told me.' Paladini says that's a departure from what Willis previously told him. Paladini told the Arizona Republic, in part: . 'McDonough allegedly overheard radio traffic between Marsh and Steed... 'Marsh told Steed to leave the 'black,' which was safe... 'Steed protested, saying the move would be dangerous... 'That is what Darrell (Willis) told me,' Paladini said. Despite his claim that Paladini got the facts of their conversation wrong, Willis does not deny speaking to the attorney. Willis says he did so after McDonough came to him because he 'wanted to get something off his shoulders.' Willis, evidently, just isn't saying what that something was. The members of the Granite Mountain Hotshots (pictured) were engulfed by wind-whipped flames on the third day of a lightning-sparked blaze that destroyed scores of homes and charred 8,400 acres in and around the tiny town of Yarnell, northwest of Phoenix . The June 30 disaster marked the greatest loss of life from a U.S. wildfire since 1933, when more than two dozen firefighters were killed battling the Griffith Park fire in Los Angeles . Nonetheless, the Arizona Republic writes, 'when Willis reported the conversation to Paladini and others, it set off a chain reaction of legal actions beginning with reports to the Arizona State Forestry Division, the Prescott City Council and the Arizona Attorney General's Office. It also led authorities to interview other potential witnesses, and prompted an unsuccessful effort to subpoena McDonough.' The purported revelation may change the outcome of a wrongful death suit filed by the families of a dozen on the hotshots last June accusing the state of negligence. It could also change the outcome of suits filed by dozens more area property owners suing the state for alleged mismanagement that led to the destruction of their property. The Forestry Division's liability might be reduced if it turns out Marsh overruled Steed's concerns over moving out of the 'black' safe zone.

Prescott City Attorney Jon Paladini claims sole survivor Brendan McDonough heard an argument between the crew leader and his deputy.
Paladini claims McDonough told his secret to former city fire chief Darrell Willis.
Willis admits McDonough came to him to 'get something off his chest' but says it wasn't about infighting that occurred before the tragedy.
McDonough has also denied the accuracy of Paladini's account, but reports of it may alter lawsuits stemming from the tragic June 2013 fire.
