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.

Illinois governor JB Pritzker signed the Sonya Massey Bill (SB1953) into law. The move comes a little more than a year after a Sangamon County deputy shot and killed Massey in her home. The law is the first of its kind in the country.
