Iris grew up in the Hyde Park area of Boston.  As frequently happens in suich areas she began running with a gang at a young age, for both protection and thrills.  Locos Muertos predominantly sells drugs/weapons and steals cars.  While Iris never had a hand in selling the "merch" her natural talents at driving were quite useful in moving it.  Eventually she was one of the lucky ones and her talents allowed her to move into higher paying jobs, at first for the gang, but eventually she graduated entirely into shadowrunning.  She still maintains a close relationship with the gang however and they know they can count on her in a pinch if they need her.
