A 15-year-old student threatened to "shoot up" Greenport High School Friday, police say.

Investigators say the teen who made the threat is a ninth grader at the high school.

Police say the same teenager was previously investigated over a prior threat against the school in May.

Greenport resident and former school board member Heath Wolf says parents need to keep talking to their children, teachers need to keep talking to their students and administrators need to keep talking to their teachers in order to get the amount of school threats under control.

"The only way we're going to get to the bottom of mental health concerns, of threats, bullying, all of the above - you have to have the hard conversations," Wolf says.

Police say the teen who made the threat is facing two charges, one for making a terroristic threat and another for aggravated harassment.
