Excerpt:
The Shelbyville chief of police and a former Tyson employee confirmed that threatening messages surfaced this week, leading to extra security at the plant.
"A couple days ago, they had a terrorist threat that was written on the bathroom walls that said 'all Americans must die,'" said a woman, who said she wanted to remain anonymous to protect her relative, who works inside the plant.
She said that she didn't see the writing herself but is aware of what's going on from others."
