The officer activated his spotlight and noticed Holland popup from the driver seat where he appeared to be moving around. Holland quickly exited the car and started moving toward the officer and "because of the circumstances and how he made the sudden movement," the officer ordered Holland back to the car. The officer approached the car and noticed a large metal hatchet and electric stun gun in the front area of the car. The officer also said he found a class A drug.

The items included an open bottle of aluminum powder, an open container of iron powder, a coil of rusted wire and an emergency jumpstart battery." Officers suspected the materials could be used to make a bomb. A Massachusetts State Police Bomb Squad Officer later confirmed that suspicion.
