Chicago plaintiff’s lawyer Antonio M. Romanucci has joined civil rights attorney Benjamin Crump in representing the family of George Floyd, whose death last week sparked nationwide protests against police brutality.

Romanucci — a founding partner at Romanucci & Blandin and the current president of the Illinois Trial Lawyers Association — stood at a press conference in Minneapolis Monday alongside Crump and two forensic pathologists as they presented the results of an independent autopsy that found three Minneapolis police officers caused Floyd’s death when they pinned him down with their knees on May 25.
