SWAT was activated shortly after 6:00 a.m. when police received a call about the man, who had allegedly indicated that he wanted to harm himself.
A female companion of the man told police that she heard what she thought was a gunshot, prompting her to alert authorities.
Police arrived on scene and, not knowing if the man was still alive and armed, set up a perimeter and evacuated nearby homes.
Then, around 10:00 a.m., the SWAT team said it was able to confirm the man was dead. They say a weapon was on the floor near the man's body.
The man who was found dead was not identified.
Classes have been canceled for the day at nearby Pitman Middle School.
