Jeffrey J. Berner, a 65-year-old White/Caucasian male, was working as a taxi driver in Chicago on January 5, 2022, when what began as a routine fare ended in a fatal shooting on the city’s Far South Side. Berner had picked up a passenger from a motel in Calumet Park and drove toward a CTA Red Line station. The trip ended in the 600 block of West 95th Street in the Washington Heights area, roughly six blocks from the station where the passenger had reportedly asked to be dropped off.
According to prosecutors, a private surveillance camera captured the final moments of the cab ride. After the taxi stopped, the vehicle could be seen rocking as some type of struggle or commotion occurred inside. Two gunshots followed while Berner was attempting to get out of the cab. The passenger, later identified by authorities as Isaiah Holliday, allegedly emerged from the rear of the vehicle wearing distinctive Nike shoes and a black jacket with shiny sleeves. Prosecutors said the surveillance footage showed Holliday approaching the driver’s side of the cab and going through Berner’s pockets twice before fleeing.
Berner remained inside or alongside the cab with the driver’s door open. Another motorist subsequently struck the open door and called police. Officers responding to the scene found Berner unresponsive with two gunshot wounds to his abdomen. He was rushed to Christ Medical Center in Oak Lawn, but he died from his injuries. His obituary later described his death as sudden and remembered him as someone with a big heart who had made many friends during his life. He was survived by his mother, daughter, grandchildren, brother, sisters and other relatives; his wife, Cathy Dukes, had died before him.
Detectives eventually focused on Holliday after investigators reconstructed the passenger’s movements. Prosecutors said Holliday had ordered the cab from a Calumet Park motel area and had checked into a neighboring motel using his own name. Surveillance footage from the motel allegedly showed him checking in and later getting into Berner’s taxi. Investigators also obtained cellphone information that prosecutors said documented Holliday’s movements on the day of the killing. Those movements were compared with GPS information from Berner’s cab and allegedly corresponded with the route the taxi traveled while transporting Holliday.
A separate armed robbery about two weeks later provided investigators with additional evidence. On January 19, 2022, prosecutors said Holliday entered a store in the 11000 block of South Michigan Avenue wearing what appeared to be the same distinctive shoes and jacket seen in the investigation of Berner’s killing. He allegedly took a bottle of Sprite from a display and carried it to the counter. When the clerk opened the cash register, Holliday allegedly displayed a firearm and stole approximately $300. He was taken into custody nearby but was initially released because the clerk could not identify the masked robber.
The investigation continued after police recovered the jacket allegedly worn during the robbery. Authorities said Holliday’s LINK card and cellphone were found inside it. A fingerprint recovered from the Sprite bottle was submitted to the Illinois State Police crime laboratory and was matched to Holliday, prosecutors said. Investigators also examined Facebook messages in which Holliday allegedly discussed the robbery. In one exchange described in court, he reportedly indicated that he was not concerned about losing a gun because it had already been connected to a killing. Prosecutors presented that statement, along with the surveillance evidence, cellphone information and cab GPS data, as part of the evidence linking him to Berner’s death.
Holliday, who was 25 at the time, was arrested and charged with first-degree murder in Berner’s killing as well as armed robbery in connection with the January 19 store robbery. At his initial court appearance, Cook County Judge Kelly McCarthy ordered him held without bail in both cases. Prosecutors also noted that Holliday had a previous drug conviction stemming from a 2019 guilty plea. The murder allegation remained a criminal charge rather than a finding of guilt.
The case appears to have remained pending for years after the arrest. Cook County Sheriff records dated April 17, 2026, still listed Isaiah Holliday as a detainee whose lead charge was murder with intent to kill or injure and showed that he had spent approximately 1,534 days in custody. Publicly accessible sources reviewed through September 2026 did not disclose a reported trial verdict or conviction in Berner’s killing, indicating that the prosecution had not yet produced a publicly reported final resolution in the sources available online.
