RedactedNarrative: On 9/4/2022 at approximately 1:50 PM, I observed a PWC with 2 occupants travelling northwest across Grass Lake on the Fox Chain of Lakes. The PWC was travelling at a high rate of speed and wave conditions were moderate with wind, and the occasional large wave from heavy boat traffic. I observed the PWC hit a large wave and both occupants get ejected. I arrived to find both occupants in the water and both appeared stunned. CPO 2 and I were able to pull both occupants in to our patrol boat. Passenger complained of chest pain and was unable to catch his breath. We secured the PWC and towed it back to the Chain of Lakes State Park with both occupants in our boat. When we arrived at the launch Fox Lake Fire Dept evaluated Passenger for injuries. He was transported to Northwestern Medicine in McHenry for further diagnosis. No damage to the vessel was sustained. The vessel was released to the registered owner who was standing by at the park
