In a police brutality case that drew national attention, Sean Grayson fatally shot the Black Springfield area woman in her home in 2024 after she had called 911 to investigate a possible prowler. His second-degree murder conviction carried a maximum sentence of 20 years.

The sentence is the maximum allowed for second-degree murder.
