Partial head found near Fox River crash; investigators seek ID

McHenry County officials are trying to identify partial human remains found near the Fox River (Colby Drive) days after the fatal Fox River boat crash that killed Magdalena Jablonska. Dental records are being used to establish an ID, as authorities have not confirmed whether the remains belong to Jablonska, who was decapitated in the collision of a 31‑foot pontoon and a smaller boat. The coroner’s office continues its investigation with other agencies; meanwhile, Richard Stevenson, 45, remains jailed on reckless homicide and aggravated DUI charges related to the crash.
