By MICHAEL BIESECKERThe parents of Alex Pretti have retained a former federal prosecutor who helped Minnesota’s attorney general convict the police officer who kneeled on George Floyd’s neck of murder. Pretti, an intensive care nurse at the Minneapolis VA Medical Center, was shot multiple times on Saturday as he was filming Border Patrol officers conducting an immigration enforcement operation. Schleicher is representing Michael and Susan Pretti pro bono, according to a family spokesman. Pretti’s younger sister, Micayla Pretti, has separately hired attorney Anthony Cotton of Kuchler & Cotton in Milwaukee, Wisconsin. Good’s family has hired the Chicago-based firm Romanucci & Blandin, which previously represented Floyd ’s family.
