The 24-year-old white reporter, who was murdered on live TV along with her cameraman, used the phrases as an intern at ­WDBJ TV in Roanoke in 2012, according to an internal complaint filed by Flanagan, who was black.

“One was something about ‘swinging’ by some place; the other was out in the ‘field,’ ” said the Jan. 21 report by assistant news director Greg Baldwin, which refers to Parker as Alison Bailey (her middle name)…

“That’s how that guy’s mind worked. Just crazy, left-field assumptions like that,” Ryan Fuqua, a video editor at WDBJ, told The Post.

“[Those words are] just common, everyday talk. [But] that was his MO — to start s- -t,” Fuqua ­explained. “He was unstable. One time, after one of our live shots failed, he threw all his stuff down and ran into the woods for like 20 minutes.”
