By now, most of us have heard about the Bastille Day Massacre where Mohamed Lahouaie Bouhlel drove a 19 ton white Renault Lorry into a crowd of people celebrating the holiday and killing 84 people. Bouhlel himself was born in Tunisia in 1985, and had a French Residency permit.
According to reports, Bouhlel had no ties to any Islamic terrorist organizations, however was depressed, had a criminal background, and he was (as usual) "a loner."
