Illinois State Sen. Doris Turner said the act will determine "necessary guardrails to ensure we have good officers on our streets."

Gov. JB Pritzker on Tuesday is expected to sign new legislation requiring more thorough background checks before hiring police officers, a law inspired by the shooting death of Sonya Massey.

Just over a year after police fatally shot Sonya Massey in her home, Illinois has introduced a police reform bill named in her memory.
