Illinois Governor JB Pritzker signed a new law requiring law enforcement agencies to conduct more thorough background checks on prospective officers, following the fatal shooting of Sonya Massey by a sheriff's deputy with a history of misconduct.

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.

The law requires extensive background checks before Illinois police agencies hire officers. It was named for Sonya Massey, who was shot and killed in her home near Springfield by a deputy who had a string of prior discipline complaints.
