He went to Sonya Massey’s home after she called 911 about a possible prowler.
During the visit, he shot Massey three times.
The shooting was recorded by a body camera and caused protests.
A jury found Grayson guilty of second-degree murder.
He received a 20-year prison sentence.
Grayson had colon cancer and asked to leave prison early for medical reasons, but that request was denied.
He later died, and officials have not said what caused his death.
Sean Grayson, a former Sangamon County sheriff’s deputy, died Sunday while serving a 20-year sentence.

Body-camera footage showed Grayson firing three shots after Massey apologized and ducked behind a kitchen counter.
The shooting prompted protests, national attention and changes to Illinois police hiring and training requirements.
