SAN DIEGO (KGTV) -- The man suspected of driving into and setting fire to a Raytheon building in San Diego last month appeared in court Wednesday.
Daniel Hector Mackinnon, 36, pleaded not guilty at his Wednesday arraignment.
Mackinnon was charged with two counts of malicious destruction of a building by means of fire in late April.
According to authorities, on April 24, an explosion occurred at the Raytheon building on the 8600 block of Balboa Avenue.

A complaint filed in federal court says surveillance video shows a Toyota Prius drive into the side of the building before a man can be seen in the back of the car.
Authorities say the man then opened the back hatch when a fireball shot from the side of the vehicle and the man fled.
According to the complaint, two empty magazine cartridges and remnants of a melted gas container were found inside the car. The Prius also had two different stolen California license plates.
