Fox River Boating Death Leads to Charges and Pretrial Detention

Record classification: Illinois criminal risk-precedent record, McHenry County Circuit Court, first verified in Q3 2026. Source basis: McHenry County State’s Attorney press release, with local court reporting used only for hearing details. Last verified posture: first appearance held, state petition for pretrial detention granted, next court date set for August 5, 2026, at 9 a.m. CT. No public docket number was available in the materials reviewed, and no source documents any connection to AI tools, generative legal filings, or AI-related legal practice.

The case is People v. Richard M. Stevenson, arising from a July 25, 2026 fatal Fox River boating collision. Stevenson was charged with aggravated operating a watercraft under the influence causing death under 625 ILCS 45/5-16, identified as a Class 2 felony, and reckless homicide under 625 ILCS 5/9-3, identified as a Class 3 felony.[1] The state’s detention petition was granted on July 27, 2026, under 725 ILCS 5/110-6.1.[1]

What The Detention Order Actually Adds

The phrase “drunken boating accident decapitation Fox River legal case” will bring many readers to this record. The legal point is narrower and more useful: the court did not treat a reported low assessment score as the end of the detention inquiry. Shaw Local reported that the defense described Stevenson’s pretrial risk assessment score as 2, while Judge Tiffany Davis Lamb still ordered him detained after reviewing the alleged conduct and prior record.[2]

The dangerousness finding rested on conduct evidence, not on the label attached to the offense alone. The state alleged that Stevenson operated a pontoon boat at about 80 mph in a no-wake zone, with passengers warning him to slow down, before the pontoon rode over another boat and killed Magdalena Jablonska, 48, a former U.S. Marine.[1] The state also cited alcohol evidence and Stevenson’s prior driving-related history.[1]

Under Illinois’ post-cash-bail framework, the court was not choosing between “score says release” and “charge sounds serious.” It was deciding whether any condition or combination of conditions could mitigate the threat identified by the state. According to the state’s attorney release, the judge explicitly rejected GPS monitoring, home confinement, and a SCRAM bracelet before ordering detention.[1]

Fox 32 Chicago likewise reported that Stevenson was denied pretrial release after prosecutors argued that conditions would not address the danger presented by the alleged conduct.[3] That reporting is useful for the hearing posture, but the principal support for the detention classification remains the official state’s attorney account.

Charges, Alcohol Evidence, And The Collision-Time Estimate

The alcohol numbers need to be kept in their proper lanes. The McHenry County State’s Attorney reported a hospital blood draw of .236 and an estimated blood alcohol concentration of approximately .200 at the time of the collision.[1] The two figures should not be collapsed into one number. The first is a test result associated with the hospital draw; the second is the state’s collision-time estimate.

The distinction matters because the detention ruling did not depend on a single isolated fact. The alleged BAC at the time of the crash was approximately 2.5 times the .08 legal limit, and it was paired with the alleged 80 mph speed, no-wake-zone setting, and passenger warnings.[1] A low risk score may describe one structured assessment output; it does not erase the court’s separate obligation to evaluate specific, alleged conduct.

The state also alleged prior driving-related offenses spanning 1997 through 2005 and a 2023 speeding violation.[1] Those entries do not prove the charged offenses in this case. They do, however, explain why the prior-history discussion mattered at a detention hearing where the court was asked to forecast whether release conditions could manage risk.

The Facts That Complete The Record

The victim was identified as Magdalena Jablonska, age 48, a former U.S. Marine.[1] The state alleged she was decapitated when Stevenson’s pontoon rode over her boat.[1] That detail explains why the case received broad attention, but it does not need to do the legal work. The detention analysis turns on charged conduct, alcohol evidence, speed, warnings, prior history, and rejected conditions of release.

The state’s attorney release also says Stevenson made the statement “my life is over,” and that two passengers left the scene by Uber before law enforcement arrived.[1] Those facts belong in the record because they were reported as part of the state’s account of the aftermath. They should not be treated as admissions to every statutory element, and they should not be inflated into findings that have not yet been made.

At this stage, the case is still at the beginning of the criminal process. The state has filed charges, the court has granted detention, and the allegations have not been tested at trial. No public material reviewed for this record supplies a trial outcome, plea, indictment posture, or full docket sheet.

Why The Low Score Did Not Control

The most common misread of this case will be procedural. A reported risk score of 2 is not the same thing as a judicial finding that release is safe. It is one input. The court still had to consider whether the facts alleged by the state showed a threat that could not be addressed by conditions.

Here, the court had before it allegations of extreme speed on the water, intoxication, passenger warnings, a fatal collision, and a history of driving-related offenses. The judge then rejected three proposed supervision tools: GPS monitoring, home confinement, and alcohol monitoring through a SCRAM bracelet.[1] For lawyers tracking detention practice, that sentence is the classification point. The order is not notable because the crash was horrific; it is notable because the court found that ordinary monitoring tools did not answer the specific risk alleged.

That does not make the case a referendum on every SAFE-T Act release decision. It is a fresh McHenry County example of a narrower proposition: under 725 ILCS 5/110-6.1, a low defense-cited assessment score did not prevent detention where the judge credited conduct-based danger evidence and rejected the available conditions described at the hearing.[1][2]

Current Status

As of Q3 2026, Stevenson has had a first appearance, remains detained under the July 27, 2026 order, and is next scheduled to appear on August 5, 2026, at 9 a.m. CT.[1] No public docket number was available in the reviewed materials.
