A Hudson Valley man was found dead inside a closet of an all-girls high school.

On Wednesday around 11:45 a.m., the Demarest Police Department was received a call from the Academy of the Holy Angels emergency radio system reporting that a contractor was found dead in a closet.

A 62-year-old contractor from Cablevision was discovered in a utility room where he was performing an installation, police say.

The deceased man was later identified as 62-year-old Paul A. Glatz, of Brewster, NJ.com reports. Glatz was performing installation work for Cablevision at the New Jersey high school.

While working at the school he had a massive heart attack and was unable to leave the closet. He wasn’t found until the next day.

Our thoughts and prays are with the family and friends of Glatz.
