Zachary Pilon, 19, pleaded guilty on Wednesday to using social media to threaten the lives of 40 people at College Notre Dame last March.
Pilon made a brief appearance to enter his plea, accompanied by his parents. He will return to court on Jan. 22 to set a date for sentencing. His lawyer, Glenn Sanberg, said the sentencing should take about two hours.
Pilon was arrested March 20, 2019 after he posted on social media his plans to harm other students at his school.
An Instagram post, Pilon had posted a threatening message: “Friday March 22nd, everyone will finally know my name ... Look out CND.” The post included a list of dozens of names titled "CND KILL LIST".
He was released on bail March 21 and charged with criminal harassment and uttering threats. His bail carries strict conditions, including a curfew and no contact with all of the people he named in his list.
