Marc looks like your typical law enforcement agent. He wears the typical trenchcoat, formal shirt, and tie topped off with the black sunglasses. While not huge a body builder it is obvious he keeps himself in shape.
Marc grew up in a rough part of Boston always in trouble due to an association with the criminal elements, but never enough for it to wind up on an official record. Once he got to High School all that changed, suddenly the classes were engaging and he picked up wrestling. This brought him out of his little neighborhood in showed him more of the world. It also helped him get into college where he double majored in Chemistry and Biology, on a wrestling scholarship. It was not his overwhelming intellegence that saw him through but his persistance.Unfortunately, given the job market at the time he was unable to leverage those degrees into anything useful. Instead he found himself stuck in a low level lab technician job, wasting both his talent and his athletic skills. This all changed on 9-11-2001. Watching the catastrophe on TV he walked out after the second plane and went straight into a recruiting office. He spent two 4 year tours in the marines and after getting out was picked up by a fellow ex-marine Mike Patterson in the Office of Enforcement and Compliance Assurance of the EPA. With his GI bill he worked his way through another college degree in criminology and is a perfect fit for being a field agent/investigator.
