A Hudson Valley teen who praised the Columbine killers on social media pleaded guilty following an investigation into a school shooting threat.

On Friday, Connor Chargois of Saugerties pleaded guilty in Ulster County Court to one count of criminal possession of a weapon.

Chargois was arrested by members of the Town of Saugerties Police Department in February after police were told he posted comments on the internet relating to “Eric and Dylan," the people responsible for the horrific Columbine School shooting. Chargois was a student at Saugerties High School at the time.

The post was shown to a teacher at Saugerties High School. The teacher brought it to the attention of the school administration, who brought it to the School Resource Officer.

In the ensuing investigation, police seized from Chargois a quantity of ammunition of varying calibers, homemade knives, machine fabricated gun parts, a prototype of a firearm that Chargois admitted he manufactured in the basement of his house, in addition to a number of completed homemade firearms in both .22 and 9mm caliber capacities, police say.

Chargois is scheduled to be sentenced in February 2019.
