Authorities are investigating a Central Michigan University hazing incident in which a member of an off-campus fraternity smeared peanut butter on the face of a student with a peanut allergy while he was passed out, according to the victim’s mother and the university.

“He could have been killed,” Teresa Seely, the mother of now-former-CMU student Andrew Seely, wrote in a Facebook post this morning.

The incident happened in October, but Teresa Seely said her son kept the matter to himself until telling family Tuesday night.

Now, she said, she wants parents and others to know about what happened to her 19-year-old son, who completed one semester at the Mt. Pleasant school before transferring because of the incident.

She declined to identify the new school to protect her son from potential retaliation.
