The family of a Streamwood man who drowned at Centennial Beach in July 2025 has filed a wrongful death lawsuit against the Naperville Park District. The case raises questions about lifeguard response, facility safety, and what public entities owe the people who use their recreational spaces.
What Happened at Centennial Beach
On July 10, 2025, Manuel Rosales entered the water with friends, intending to swim to a floating dock in the deep end of the former quarry. His friends reached the dock and realized he was not with them. They searched, then alerted lifeguards. Police responded to a missing person report at 5:43 p.m. Lifeguards recovered Rosales from the water at roughly 6:06 p.m., unresponsive. He was pronounced dead at a nearby hospital, and the DuPage County Coroner’s Office ruled the death an accidental drowning.
His family sees it differently. The lawsuit, filed in DuPage County Circuit Court in May 2026, alleges willful and wanton conduct contributed to his death, according to reporting from NCTV17.
What the Lawsuit Alleges
The complaint focuses on how staff handled the emergency once they knew a swimmer was missing. According to the filing, the response fell short in several ways:
- Staff allegedly treated the report as a land-based missing person situation, conducting announcements and bathroom checks rather than immediately searching the water
- Lifeguards were reportedly told Rosales was last seen in the deep end, where he was ultimately found
- The delay allegedly left him submerged for a prolonged period
- The beach’s low-visibility water made it difficult to spot a swimmer in distress
The suit also points to a 2018 near-drowning at the same facility. In that incident, lifeguards allegedly dismissed a report of a missing swimmer as a prank before finding a 13-year-old boy unconscious at the bottom of the water. The family argues the district knew its protocols needed to change and failed to act.
The Naperville Park District maintains the death was an accident and has expressed support for its lifeguards’ rescue efforts.
Why the Willful and Wanton Standard Matters
Claims against park districts and other local government bodies in Illinois face hurdles that ordinary negligence cases do not. Immunity protections often shield public entities from liability for simple carelessness. To recover, families frequently must show willful and wanton conduct, meaning a conscious disregard for the safety of others. That is a higher bar, and it explains why this lawsuit is framed the way it is.
Timing matters too. Claims against local government entities in Illinois generally carry a one-year filing deadline, which is substantially shorter than the standard two-year period that applies to most personal injury and wrongful death claims. Families who wait can lose their rights entirely, no matter how strong the underlying facts may be.
Anyone weighing a claim like this should speak with a Naperville, IL wrongful death lawyer before deadlines pass.
What Families Can Recover
Under the Illinois Wrongful Death Act, surviving family members may pursue damages for the losses the death caused them. That can include lost financial support, loss of companionship, and grief and mental suffering. Every case turns on its own facts, and the value of a claim depends on the evidence, the defendant, and the applicable legal standards.
The Rosales family has said its goal goes beyond money. They want accountability and changes that protect other swimmers. Litigation is often the only mechanism that forces those answers into the open.
