KENOSHA, Wis. — Kenosha County Assistant District Attorney Morgan Millar secured a guilty verdict Wednesday, October 21, 2026, in a first-degree intentional homicide case involving the 2023 shooting death of a Kenosha man. The verdict marks a significant courtroom accomplishment for the relatively new prosecutor, who earned high praise from Kenosha County District Attorney Xavier Solis for her preparation, dedication and determination.

Antonio D. Summers, 40, of Waukegan, Illinois, was found guilty in connection with the April 23, 2023, killing of DeShun Montreal Jackson, 44, of Kenosha. Jackson was shot inside an apartment building in the 1600 block of 60th Street. The case, which has been pending for approximately three and a half years, was prosecuted by Millar before Kenosha County Circuit Court Judge Jason Rossell.

District Attorney Praises Millar’s Work
Solis, who took office in January 2025, offered strong praise for Millar in a statement to Kenosha County Eye on Wednesday, highlighting the work required to successfully prosecute a serious homicide case.
“ADA Morgan Millar earned this verdict through hard work, thorough preparation, and a strong command of her case. She made sure she had everything she needed to present the evidence effectively and approached the trial with passion and determination. She is a talented, dedicated prosecutor who takes her responsibility to victims and this community seriously. I am proud of her work and proud to have her in the Kenosha County District Attorney’s Office,” Solis said.
Solis also addressed the circumstances surrounding the murder and the issue of violent offenders traveling into Kenosha County from neighboring Illinois.
“This case is another example of an Illinois resident coming into Kenosha County and committing a violent crime. Here, the defendant took the life of a Kenosha resident. We will aggressively prosecute those who bring violence into our community and hold them accountable,” said District Attorney Xavier Solis.
Homicide prosecutions are among the most consequential cases handled by a district attorney’s office. They frequently involve extensive police investigations, witness testimony, forensic evidence and complicated legal questions. Prosecutors must present that evidence to a jury while meeting the state’s burden of proving guilt beyond a reasonable doubt.
For Millar, Wednesday’s verdict represents an important professional milestone and an opportunity to demonstrate her abilities in one of the most serious types of criminal cases prosecuted in Wisconsin.
A Fatal Shooting In Kenosha
According to Kenosha Police, officers responded to an apartment complex at 1615 60th Street at approximately 2:14 a.m. on April 23, 2023, following reports of a shooting. Officers discovered Jackson suffering from gunshot wounds. Despite lifesaving efforts by Kenosha police officers and Kenosha Fire Department personnel, Jackson died at the scene.
Investigators determined that the shooting was not a random act of violence. Summers was subsequently identified as a suspect, and a warrant was issued for his arrest. On June 3, 2023, Chicago police arrested Summers in Illinois, where he was initially held pending extradition to Wisconsin.
Summers also encountered legal trouble during efforts to apprehend him. According to the Lake County Sheriff’s Office, Summers fled from deputies on June 1, 2023, and broke free from an officer attempting to arrest him. The officer suffered a leg injury, resulting in an additional felony charge of resisting a peace officer in Illinois. A $300,000 arrest warrant was issued in that case.
The Wisconsin criminal complaint also identified Summers as having a prior felony firearm conviction in Lake County, Illinois, from June 2020.
Remembering DeShun Jackson
Jackson was more than the victim in a homicide prosecution. He was a husband, father, grandfather and longtime member of the Kenosha community.
Born September 2, 1978, in Chicago, Jackson was raised in Kenosha and graduated from Mary D. Bradford High School. According to his obituary, he enjoyed basketball and football and was an enthusiastic Chicago Bears and Chicago Bulls fan.
His family remembered him as a charismatic storyteller with a sense of humor who loved spending time with those closest to him. He left behind his wife, children, grandchild and numerous other relatives and friends.
Wednesday’s verdict comes more than three years after Jackson’s death, bringing an important measure of accountability in a case that began with a fatal shooting in the early morning hours.
Sentencing Scheduled For December
Summers is scheduled to appear before Judge Rossell for sentencing on December 16, 2026, at 3 p.m. A conviction for first-degree intentional homicide in Wisconsin carries a mandatory life sentence, although the court determines eligibility for possible extended supervision under applicable state law.
For Millar, the verdict is a significant achievement in her prosecutorial career. For the Kenosha County District Attorney’s Office, it represents the conclusion of another major homicide trial, with sentencing still to come. And for Jackson’s family, the verdict marks a major development in a case that has remained unresolved for more than three years.
