Park said an investigation by the Union County Prosecutor’s Office’s Special Prosecutions Unit and Kean University police found that McKelvey, a self-proclaimed activist, participated in a student rally to raise awareness of racism on college campuses on Nov. 17, but left midway through and walked to a computer station in a university library.

Once there, McKelvey allegedly created an anonymous Twitter account –  @keanuagainstblk – and began posting threats of violence against black Kean students.

The first message around 10 p.m. said “kean university twitter against blacks is for everyone who hates blacks people” and a tweet about there being a bomb on the campus, and then continued with several other tweets about shooting black students at the university.
