ELIZABETH - A self-proclaimed activist has admitted to posting a series of racially threatening Twitter messages targeting students at Kean University last fall.

Kayla McKelvey, 25, of Union Township, pleaded guilty to a charge of creating a false public alarm.

An investigation found that McKelvey, a Kean University alumnus, participated in an on-campus student rally regarding racial issues last November. She then left the rally, set up an anonymous Twitter account, and posted messages threatening to kill black students at the university. 

McKelvey then returned to the rally and told students about the posts. At the time, the posts sparked protests and calls for the university president to resign.

McKelvey is set to be sentenced on June 17. She faces up to 90 days in jail and may have to pay $82,000 in restitution to cover the cost of the police response.
