With Monday's departure of reporter Jennifer Robison from the Las Vegas Review-Journal, none of the three journalists who helped uncover the secret sale of the newspaper to casino magnate Sheldon Adelson remains at the company.

Robison, who took a job in communications for Pacific Gas and Electric Co. in San Francisco, left after the exits of her former colleagues, reporters Howard Stutz and James DeHaven.

After Adelson and his family bought the Review-Journal late last year in a secret transaction, the journalists in the paper's newsroom turned their investigative reporting skills inward. NPR's media correspondent David Folkenflik said the deal was "initially intended to keep the new owners' identity secret from the public and the newsroom itself." He wrote:

"The paper's reporters covered the mystery and subsequently identified the Adelsons despite the efforts of the paper's publisher to delay and soften the coverage. The paper's editor was among those who subsequently left. Promises of scrupulous disclosure of the Adelsons' interests were scaled back."

DeHaven was already on his way out when the story broke, as he told CNN last year. He now works as a Montana statehouse reporter for the Helena Independent Record.

Howard Stutz, a longtime casino industry reporter, announced last week that he was leaving the newspaper to work with the Las Vegas law firm Greenberg Traurig. As NPR member station KNPR reported:

"After 11 years covering the gaming industry for the Las Vegas Review-Journal, Howard Stutz has stepped down."Stutz's tenure as a reporter and columnist in Las Vegas lasted some 30 years, with time spent with both the Las Vegas Sun and Review-Journal."His latest tenure at the Review-Journal included covering a devastated casino industry following the Great Recession in 2008."And, being part of the team of reporters who confirmed Sheldon Adelson's $140 million purchase of Nevada's largest newspaper."

A flood of reporters and editors left the newspaper after it was bought by the Adelson family, citing curtailed editorial freedom, murky business dealings and unethical managers. As David reported in April, one veteran columnist, John L. Smith, left the paper because he couldn't write about "two of the state's biggest players, including his newspaper's new owner."

"Smith had written columns for the Review-Journal for nearly three decades, with a frequent focus on Adelson, one of the most powerful figures in Nevada gambling and national Republican politics. The billionaire sued Smith for libel over a passage in a 2005 book about power players of Las Vegas."Smith prevailed in court, but paying the fees helped bankrupt him. (NPR told that remarkable story, including a rabbi's offer of a secret $200,000 payoff from Adelson for Smith to admit libel, earlier this year.) Years later, the case has helped trigger the end of Smith's career at the Review-Journal, as his new bosses cited it as a conflict of interest...."Smith says new management implemented a new policy earlier this year: He could not cover anything to do with Adelson. The then-acting editor, Glenn Cook, regretfully conveyed the decision from publisher Craig Moon. Smith says he took issue: 'I said, "He's the one who sued me, he lost, and I'm conflicted?" '"Smith says Cook told him: 'You can't do it or you'll be fired.' "

Last week, the newspaper's features editor, Stephanie Grimes, announced her departure, too, via a post on Medium. She said the journalists in the newsroom "felt paranoid, communicating in whispers and texts about the latest rumors lest we were overheard by — well, we didn't know." Grimes wrote:

"I believe in the power of journalism and I believe in the great reporters in the RJ newsroom — including on my own team. But as much as I love the idea of the Review-Journal, my trust in the company as an institution has died a slow death over the past five months. Its management has failed on too many occasions to live up to the standards we so rigidly hold others to on a regular basis."Copyright 2016 NPR. To see more, visit http://www.npr.org/.
