GLOUCESTER CITY, NJ (March 26, 2022)—Dwayne A. Vandergrift Jr. who was accused of detonating a homemade bomb at GCity Cross-fit gym, in the summer of 2020, pleaded guilty on Friday, March 25 in U.S. District Court, Camden City, according to the Courier Post. 

The gym is surrounded by residential homes. Those living in the area said they were awakened by a
loud noise; some said it was around 3:30 AM while others told CNBNews it was 4 AM. Two days later, on Friday, August 28, 2020, Vandergrift Jr., was arrested at his home in the 700 block of Powell Street.

The blast at 512-514 South Broadway knocked out the front door of the property.  The large glass windows on either side of the door were not damaged by the blast. A tree in front of the building was blown over.  Why Vandergrift committed the act was never explained by authorities. 

After he was arrested U.S. Attorney Craig Carpenito released the following information.

During the early morning hours of Aug. 26, 2020, Vandergrift placed an explosive device on the front door of a local gym near his home in Gloucester City. Security camera footage recorded Vandergrift fleeing the area moments before the device exploded, badly damaging the front door and shattering its glass. 

On Aug. 28, 2020, federal and local law enforcement officers executed a search warrant at Vandergrift’s home and found substantial quantities of bomb-making materials, numerous weapons, including an unregistered short-barreled rifle, several tactical vests outfitted with body armor and loaded 30-round ammunition magazines, and a marijuana grow operation containing approximately 85 marijuana plants. Upon examining Vandergrift’s personal computer devices, investigators discovered that he had recently researched how to construct and utilize various explosive devices, including pipe and pressure cooker bombs.
