Families had packed the water, boats drifted through the summer sunshine, and dozens of people were enjoying one of the busiest weekends of the season. Then, in a matter of seconds, witnesses watched a massive high-powered pontoon boat roar through a clearly marked no-wake zone at what prosecutors say was nearly 80 miles per hour—far faster than anyone believed possible in that stretch of river. The collision that followed was so violent it instantly transformed an ordinary family outing into one of the most horrifying boating tragedies the region has seen in years.
According to prosecutors, 45-year-old Richard Stevenson had spent much of the day drinking before climbing behind the wheel of his 31-foot pontoon boat. Witnesses later told investigators they had already noticed him speeding recklessly up and down the river hours before the fatal impact, describing repeated dangerous passes that left other boaters alarmed. Surveillance footage and eyewitness accounts would later become central pieces of evidence as authorities reconstructed the terrifying final moments before the crash.
Investigators allege Stevenson never slowed as he approached another vessel carrying a 48-year-old woman and her husband. Instead, his boat struck the smaller craft with such overwhelming force that it rode up over the vessel. The woman suffered catastrophic injuries and died at the scene, while her husband survived the collision with injuries that authorities say will likely leave lasting physical and emotional scars. Court proceedings later revealed the shocking severity of the impact, turning the case into national headlines almost overnight.
The horror did not end with the crash itself.
Prosecutors say Stevenson made his way ashore after the collision, where witnesses recalled him crying that his “life was over.” Investigators also alleged that others who had been aboard his boat left the immediate area before emergency crews arrived, prompting additional scrutiny as authorities pieced together exactly what happened in the chaotic minutes following the collision. A court-ordered blood test later allegedly showed his blood alcohol concentration measured approximately 0.20—more than twice Illinois’ legal limit for operating a boat.
But perhaps the detail that stunned the courtroom most had nothing to do with that afternoon.
Instead, prosecutors pointed to Stevenson’s history.
Court records showed a long list of prior offenses, including multiple DUI convictions, reckless driving violations and repeated speeding offenses stretching back decades. During the detention hearing, a prosecutor described him as “a ticking time-bomb,” arguing that the deadly collision was not an isolated lapse in judgment but the tragic culmination of years of dangerous behavior that had repeatedly gone unchecked. The judge ultimately ordered Stevenson held without pretrial release, finding he posed an ongoing threat to public safety.
As investigators continue preparing the criminal case, many questions remain unanswered. Why was someone with such an extensive driving history still operating a high-powered vessel capable of reaching extraordinary speeds? Could earlier intervention have prevented the disaster? And what exactly happened during the moments before impact that transformed a routine summer outing into a tragedy that devastated an entire family?
Those answers may emerge as prosecutors continue building their case. For now, however, one haunting reality overshadows everything else: investigators believe the warning signs had existed for years—and they are now examining whether those overlooked red flags tell an even bigger story than the crash itself.
