Two Pennsylvania teens are facing charges in South Brunswick Wednesday after they unwittingly provided damaging evidence of their crimes.

Police say Gary McIntyre and Kyle Lyons, both 19 years old, turned an empty office complex on Ridge Road into their own personal de-construction zone. Investigators believe the teens ransacked the complex and set several fires to it. According to police, the teens were there more than a dozen times and in some cases videotaped their crimes.

Lyons and McIntyre face charges of second-degree arson, burglary and criminal mischief in the Garden State. They could also face charges in Pennsylvania. Police expect to arrest two other juveniles for the damages. They say even more people may be involved in the vandalism.
