Former Sangamon County deputy Sean Grayson is asking a judge to toss his conviction and give him a second shot in court, filing a motion Tuesday that seeks a new trial after his October second-degree murder conviction in the death of Sonya Massey. His legal team argues the jury was unfairly swayed by what it heard and what it did not get to hear, pointing to post-shooting comments captured on body-worn cameras and the exclusion of other evidence. Grayson is set to be sentenced on Jan. 29, 2026, and faces up to 20 years behind bars.
Defense Slams Judge’s Calls On What Jury Heard
In the new filing in Peoria County, defense attorneys Daniel Fultz and Mark Wykoff contend the judge mishandled key evidence. They say jurors should never have heard Grayson’s disparaging remarks after the shooting, and they argue the court wrongly blocked testimony about a neighbor’s claim that Massey hit someone with a brick the day before. The motion insists that "events occurring after an officer’s decision to use force have no bearing on whether that use of force was reasonable or justified," and the defense team told reporters the excluded brick incident could have "swung the verdict in the defendant’s favor," according to the Chicago Sun-Times.
What Jurors Saw Before Returning A Murder Verdict
Across a weeklong trial in Peoria, jurors took in hours of body-worn camera footage before convicting Grayson on Oct. 29 of second-degree murder, finding that he acted unreasonably despite his claim of self-defense, according to the Associated Press. The video shows Grayson threatening Massey and, after firing the fatal shot, telling his partner not to render aid, stating "she’s done" and that it was "a head shot," lines later aired in television coverage. All of it was weighed by a 12-person jury drawn from Peoria County.
Prosecutors Shrug Off Retrial Bid As Routine
Sangamon County State’s Attorney John Milhiser brushed off the defense motion as little more than lawyering 101, calling the request for a new trial "standard practice" and saying it did not offer a convincing argument, as reported by the Chicago Sun-Times. Grayson’s formal sentencing is locked in for 9 a.m. on Jan. 29, 2026, in Sangamon County. Local coverage has noted he could receive up to 20 years, although Illinois law allows second-degree murder sentences to include probation or a shorter term, depending on the judge, per WAND TV.
Motion Sets Stage For Long Legal Fight
Grayson’s challenge is a familiar move in serious criminal cases. Requests for new trials rarely succeed at the trial-court level, but they often lay the groundwork for a longer appellate fight, legal analysts told local reporters, according to Illinois Times. If the judge denies this motion, Grayson’s attorneys can still take procedural and constitutional arguments to higher courts, a process that could extend well past the January sentencing date.
Fallout From Massey’s Killing Still Reverberates
Massey’s death has not faded from public view. Her killing prompted county-level reviews, shifts in hiring and training practices, and a civil settlement that kept a spotlight on local policing, according to Reuters. Earlier in the case, Hoodline reported that the trial ignited national outcry, and we will be watching the latest filings and hearings as the case grinds toward sentencing.
