Chicago, IL (June 26, 2026) – One woman died, and at least four others were seriously hurt on Thursday night, June 25, after two boats collided on Lake Michigan near Monroe Harbor. The crash was reported around 11:45 p.m. near downtown Chicago.
The Coast Guard said 14 people were involved. Five people were taken to hospitals in serious to grave condition.
Three people, including a woman in grave condition, were taken to Northwestern Hospital. Two others were taken to Stroger Hospital.
The Cook County Medical Examiner’s Office later identified the woman who died as 26-year-old Johanna H. Gregory. Nine other people declined treatment at the site.
Both boats were described as recreational vessels. One was towed to Queens Landing near Buckingham Fountain, and the other was taken to the Chicago police Marine Unit headquarters.
Investigators are reviewing what caused the collision on Lake Michigan. We extend our sincere condolences to Gregory’s family and loved ones and hope the injured people recover safely.
Why Nighttime Boat Crashes Can Be Especially Dangerous
Nighttime boat crashes can be harder to avoid because visibility on the water is limited. Boat operators may have to rely on lights, sound, distance, and navigation rules to judge where another vessel is moving.
Collisions on open water can also lead to serious injuries because people may be thrown, struck by hard surfaces, or fall into the water. Cold water, darkness, and distance from shore can make rescue work more difficult.
When several people are involved, emergency crews may need to quickly assess injuries and move patients to different hospitals. Investigators may review vessel damage, lighting, speed, location, and witness statements to understand how the boats came together.
