A Cook County judge sentenced 52-year-old Henry Graham to nine years in prison for an unprovoked punch that killed Northern Trust Corporation vice president Russell Long on Michigan Avenue in 2023, a case that laid bare both police missteps and the limits of Illinois homicide law. Graham struck the 53-year-old Long from behind without warning, and Long died 13 days later from the resulting head injuries.
The attack happened on June 29, 2023, as Long walked past the Cartier store at 630 N. Michigan Avenue near Ontario Street, according to CBS News. Graham ran up behind him and struck the back of his head, and Long suffered facial and skull fractures along with bleeding of the brain before he died at Northwestern Memorial Hospital, according to the Chicago Sun-Times. Witnesses identified Graham to Chicago police immediately after the attack, and he later admitted to hitting Long, though he claimed Long had bumped into him first, the Sun-Times reports, citing police.
Officers Let Graham Walk Away, Then He Struck Again
Despite the on-scene identification, Chicago police released Graham without arresting him. Four CPD officers were later hit with internal disciplinary suspensions ranging from two to five days for failing to arrest Graham or file a complete incident report, even though eyewitnesses had pointed officers to Graham as he sat on a nearby fire hydrant, per CBS News. Witnesses told the outlet that officers had been watching a television show on a tablet inside their squad car when approached.
In the months before his eventual arrest for Long's death, Graham was accused of attacking other people, according to police reports cited by the Sun-Times. CBS News reported that Graham was arrested on September 23, 2023, in Evanston for battering a business owner and biting police officers, then was released on bond before he was arrested again on October 3, 2023, for hitting a man with a broom handle outside Wrigley Field. He has a long record of convictions for punching and kicking people, and he still faces active court cases alleging he attacked an Evanston police officer and destroyed jail property, per the Sun-Times.
Trial Testimony and the One-Punch Legal Barrier
Prosecutors originally charged Graham with first-degree murder, but Cook County Circuit Judge Charles Burns instead found him guilty of the lesser charge of involuntary manslaughter following a bench trial in June. At trial, eyewitnesses Eric Arrigo and Andrew Meza — roommates who were walking on Michigan Avenue at the time — testified that they saw Graham sprint up from behind Long and land an unprovoked blow to the back of his head, according to the Sun-Times.
Defense attorney Celeste Addyman argued that Graham believed he had been provoked, but Burns found that argument unpersuasive, per the Sun-Times. Defense attorneys also argued that under Illinois case law, Graham could not have expected a single punch to kill Long. Illinois appellate and Supreme Court precedent spanning nearly a century holds that a single, unarmed punch generally does not establish the legal intent required for a first-degree murder conviction, as CWB Chicago explains — Illinois courts have found that a person cannot reasonably anticipate a single fist blow will cause death.
That precedent isn't limited to Graham's case. CWB Chicago reports that in a similar Cook County case this July, Jamie Miller was sentenced to five years in prison after pleading guilty to involuntary manslaughter for a fatal single punch outside the River North House of Blues in November 2023; prosecutors dropped a first-degree murder charge there for the same legal reason.
Sentencing Near the Statutory Maximum
Involuntary manslaughter is a Class 3 felony under Illinois statute 720 ILCS 5/9-3, carrying a standard penalty of two to five years, though extended-term provisions allow up to 10 years for defendants with qualifying prior felony convictions, according to DRD Law. Graham's prior criminal history made him eligible for that extended term, which explains why his nine-year sentence landed near the statutory ceiling. Assistant Cook County State's Attorney Sean Brady had sought a 10-year sentence, per the Sun-Times.```
Because Illinois truth-in-sentencing guidelines apply day-for-day credit to involuntary manslaughter under 730 ILCS 5/3-6-3, Graham will serve roughly half of his nine-year term rather than the full sentence mandated for first-degree murder, DRD Law notes. He will also complete one year of mandatory supervised release after leaving prison.
Burns told the court the random nature of the attack required a stiff sentence and said society needs to be protected from Graham, according to the Sun-Times. Graham has a documented history of severe schizophrenia, mental illness and violent behavior, the paper reports. He told the court he never thought he would be responsible for laying someone to rest; he initially declined to appeal his manslaughter conviction but later agreed to do so.
A Family's Grief and a Victim Remembered
Long's brother, Daniel Long, wrote to the court that his brother's death was horrific and described him as unrecognizable in the intensive care unit, per the Sun-Times. Kristen Maurice wrote that she still cannot go near Michigan Avenue because she and Russell Long had walked there countless times together. Long had served as a vice president at Chicago-headquartered Northern Trust Corporation and was walking near his own office area when the attack occurred, according to the Chicago Sun-Times.
State Task Force Targets Mental Health Gaps in the Justice System
The case has unfolded alongside a broader state push to address how Illinois handles defendants with severe mental illness. The Illinois General Assembly passed a measure in 2025 addressing mental illness among people charged with crimes, and the governor signed it that same year, establishing a task force on evaluation and treatment, per the Sun-Times. That legislation, Public Act 104-0318, created the Fitness to Stand Trial Task Force to confront severe bed shortages in state psychiatric hospitals, where mentally ill defendants can wait months in county jails, according to IPM Newsroom. The task force includes members from the General Assembly, the courts, law enforcement and the mental health system.
On the same day Graham was sentenced, the task force approved recommendations addressing evaluation and treatment processes, and the committee is expected to vote next week on how to pay for them, per the Sun-Times. The task force aims to improve how officials determine whether defendants with mental illness can receive outpatient treatment instead of waiting in jail for a state mental-health-facility bed, and it also aims to keep people with brain disorders such as Alzheimer's disease out of state mental hospitals. Illinois has a persistent lack of state beds for defendants needing mental-health evaluation and treatment, and the task force must deliver a report by November 1.
