A U.S. Marine Corps veteran has died following a devastating boating collision on Illinois’ Fox River, with prosecutors alleging the crash was caused by an intoxicated boater traveling at extreme speed through a restricted area.
The victim’s family is now mourning the loss of a woman they describe as compassionate, devoted to helping others, and deeply committed to animal welfare.
Fatal Collision Sparks Criminal Investigation
Authorities say the collision occurred Saturday afternoon on the Fox River near McHenry, roughly 60 miles northwest of Chicago.
Prosecutors allege that 45-year-old Richard Stevenson was operating a 31-foot pontoon boat when it struck a smaller 20-foot recreational vessel from behind.
According to investigators, Stevenson entered a designated no-wake zone before accelerating to approximately 80 mph and colliding with the other boat.
The impact proved fatal for passenger Magdalena Jablonska, 48, who died at the scene.
Her husband, who was also aboard the vessel, sustained injuries and was transported to a hospital. Officials have not publicly released details about his condition.
Prosecutors Allege Alcohol Played a Major Role
Court filings allege Stevenson had a blood alcohol concentration of 0.20 after the crash—more than twice Illinois’ legal limit for operating a watercraft under the influence.
Investigators further claim witnesses told police Stevenson consumed multiple shots of whiskey before the incident.
Two passengers who had been aboard his boat reportedly left the scene before first responders arrived but were later interviewed by law enforcement.
Stevenson has been charged with two counts of aggravated driving under the influence causing death and one count of reckless homicide.
Prosecutors also cited his previous history of DUI convictions, reckless driving offenses, and multiple speeding violations during detention proceedings.
Authorities Describe Defendant as Repeat Dangerous Offender
During the detention hearing, prosecutors argued that Stevenson posed a longstanding danger to public safety due to his driving history.
Deputy Chief Brian Miller characterized the defendant as “a ticking time bomb,” telling the court that the long-feared consequences ultimately unfolded on the Fox River.
State’s Attorney Randi L. Freese said her office intends to aggressively pursue the case, emphasizing that lakes and rivers should remain safe places for families rather than locations where impaired operation leads to tragedy.
Family Honors Marine Veteran’s Legacy
Jablonska’s relatives have remembered her as someone whose life centered on service to others. After emigrating from Poland to the Chicago area as a child, she joined the U.S. Marine Corps immediately after graduating from high school, according to her family.
Her sister, Michelle Macias, said Jablonska consistently placed the needs of others ahead of her own and described her as one of the kindest people she had ever known.
Family members also said she had a lifelong passion for helping animals, particularly rescue dogs, and regularly supported local shelters.
Donations Launched in Her Memory
To honor her legacy, Jablonska’s brother created an online fundraising campaign directing donations to a local animal shelter instead of personal memorial gifts.
In the campaign, he described his sister as “the sunshine in every place she went” and said one of her greatest joys was caring for dogs in need.
Her brothers also shared emotional tributes on social media, thanking supporters for their condolences and asking the public to remember Jablonska in their prayers while funeral arrangements are being finalized.
Investigation Continues as Family Seeks Justice
The McHenry County Coroner confirmed Jablonska died instantly in the collision. Local reports indicate authorities continued recovery efforts following the crash.
Meanwhile, investigators are continuing to examine the circumstances surrounding the fatal incident as prosecutors prepare their case against Stevenson.
The allegations against the defendant have not yet been proven in court, and he remains presumed innocent unless and until proven guilty. His reported connection to a local crane service business has not been linked by authorities to the criminal investigation.
