Mexicantown Massacre

The Mexicantown Massacre is a major event taking place prior to Deus Ex: Human Revolution.

Background
Sometime prior to 2027, a mechanically augmented fifteen-year-old criminal posed a potential threat in Mexicantown. Adam Jensen was given the order to fire, but refused to carry it out. The order was passed on to his team commander, Wayne Haas, who followed it, killing the boy and sparking violent, city-wide riots. As a result of this, Jensen chose to leave SWAT, but his former superiors used him as a scapegoat, blaming him for the shooting and the riots.

In Deus Ex: Icarus Effect, Anna Kelso is told by the Juggernaut Collective about possible events orchestrated by the Illuminati. The shooting of the augmented teenager in Detroit is mentioned, indicating the conspiracy benefited from the incident.
