Third Missouri man charged with posting Yik Yak threats against college campus

Prosecutors have charged a third Missouri man with posting online threats to attack a college campus.

Nineteen-year-old Tyler Bradenberg, of St. Louis, was charged Thursday with a felony count of making a terrorist threat. An arrest warrant was issued for him.

Authorities say Bradenberg posted "I'm gonna shoot up this school" on the anonymous messaging app Yik Yak on Wednesday. It was apparently aimed at the Missouri University of Science & Technology in Rolla, where he studied chemical engineering for a semester last fall.

A Rolla detective says Brandenberg admitted he posted the threat. An S&T spokeswoman says technology was used to try to make it appear the post was made from the Rolla campus, but it wasn't.

In two recent cases, Missouri college students were charged with posting threats on Yik Yak specifically against African-Americans.

The threats followed protests over the University of Missouri's handling of racial issues that helped force two top officials to resign. Many black students on the Columbia campus said this week that they feared violent attacks from whites at the school.

On Thursday, the Nodaway County prosecutor charged Connor B. Stottlemyre, 19, of Blue Springs, with making racist threats on social media. Stottlemyre, a freshman at Northwest Missouri State University, was arrested at his dormitory.

The day before, the Boone County prosecutor charged a 19-year-old Lake St. Louis man with allegedly making an online threat targeting African-Americans on the University of Missouri’s campus. Hunter M. Park was arrested at the Missouri University of Science & Technology campus in Rolla.
