A case against a Grove City College student accused of posting a threatening message on Snapchat in February has been withdrawn, according to court information.

The docket for Mercer County District Magistrate Douglas Straub showed that the case against Ellen Ida Otterman, 21, was withdrawn on Wednesday following a hearing scheduled for that morning. The docket also indicated the case was closed.

Otterman, of Barre, Vt., was arrested Feb. 8 after authorities were alerted to a selfie she allegedly posted on Snapchat. The image showed Otterman wearing a face mask and hoodie with the caption: "Am I ill or about to shoot up a school? Stay tuned for updates."

Snapchat reportedly provided investigators with GPS data placing Otterman on the Grove City College campus at the time the message was sent. She was taken into custody, leaving the Pew Fine Arts Center.

According to an affidavit, Otterman admitted to posting the photo and text after waiving her Miranda rights. She was subsequently charged with terroristic threats, a first-degree misdemeanor, and disorderly conduct, a third-degree misdemeanor.

Grove City College officials previously stated that police determined Otterman's post was intended as a joke related to a friend's comment about her appearance and the fact that she was suffering from the flu. In an email sent to the campus community in February, the college's Vice President for Student Life, Larry Hardesty, said the post was directed to a small group of friends hundreds of miles away.

The reason for the withdrawal of the charges was not immediately clear.
