Thin on the right so far
None of the 7 outlets with a published leaning rating that ran this story are rated right.
This story is still being watched, so it is a count and not yet a finding. Coverage keeps arriving for hours after an event, and a side that has published nothing this morning may publish by tonight. If it is still true when we stop checking, we will say so plainly.
Former Illinois Deputy Sean Grayson died in prison on 23 August 2026. He was serving a 20-year sentence for the 2024 shooting death of Sonya Massey. Grayson had been convicted of second-degree murder.
Grayson had been seeking medical release from prison, citing stage 4 cancer. His attorneys had filed for release under the Joe Coleman Act in May. Massey's family stated that Grayson's death does not bring Sonya back, and wished his family peace.
Grayson maintained that Massey attacked him with a pot of boiling water. According to reports, Massey had called police to report a prowler, and Grayson entered her home to question her. Massey had a pot of boiling water on the stove. Grayson directed her to remove it, and as she did, he drew his weapon and fired three times, striking Massey in the head. A letter from Milhiser stated that Grayson's temper and willingness to escalate minor misunderstandings showed he posed a danger.
Disagreement on Grayson's claims
Grayson maintained that Massey attacked him with a pot of boiling water. ABC7 Chicago reported that in his hand-written application for medical release, Grayson did not show remorse and maintained this claim. The same report noted that Milhiser's letter pointed out there was a kitchen island and several feet between the pair when Grayson fired.
What the coverage left out
None of the left-rated digests mention that Grayson had been seeking medical release due to stage 4 cancer. None of the centre-rated reports mention that a state panel had unanimously denied Grayson's request for early medical release three weeks prior to his death.
