St. Petersburg Police Chief Anthony Holloway said during a press conference that Kyle Hill, who was initially charged with DUI manslaughter and vehicular homicide, is now facing charges of first-degree murder, attempted first-degree murder and more, for a crash on Sunday night that left a woman dead and her boyfriend severely injured.
