Leonel Campbell Ross O'Bryan (1857–16 July 1938), known under the pen name Polly Pry, was a controversial reporter for The Denver Post and later as a freelancer in the late nineteenth and early twentieth centuries.
During the confrontation, the attorney, W. W. Anderson, pulled a gun and shot both of the men; as he prepared to shoot again she jumped in front of Harry Heye Tammen, trying to shield him.
[1] When union workers boycotted The Denver Post for her stance on labor issues and immigration, she founded her own paper, Polly Pry.
The incident with Anderson (who was not named, and called "Gunman" in the credits) was included, but after she begins telling Packer's story, she does not appear again in the film, involved or otherwise, and the shooting is not mentioned again.
The Musical featured Toddy Walters in the role, which went more deeply into her involvement with the case but ignored the fact that she was married in order to make her a love interest for Packer.
