The indictment claims the group committed three murders and two attempted murders between 2015 and 2017.

Lozoya, a 21-year-old nicknamed "Saint," and 25-year-old Martinez, otherwise known as "Ghost," were both charged in 2017 with the murder of Crispin Coliz, who was on his way home from a Chicago Bulls game in December 2016 when he was shot.
