A 42-year-old Nigerian woman, Olasinmibo Abosede, fondly called Sinmi, has been found dead in Illinois, United States.
The woman, who had been missing since July 30, 2025, was found dead in the Springbrook Prairie Forest Preserve belonging to her.
A joint statement issued by the Forest Preserve District of DuPage County and the Naperville Police Department on Thursday, August 14, said the body was located at about 1:55 p.m. near 83rd Street and Chandelle Drive.
Officers responding to a call were guided through thick grass to the spot where the remains were found, the statement said.
Investigators said the clothing on the body matched what Abosede was last seen wearing.
Naperville Police Chief Jason Arres said: “While we believe the individual to be Sinmi, the final confirmation will be made by the DuPage County Coroner’s Office.
“We are deeply saddened by this loss and extend our sincere condolences to the Abosede family during this difficult time.
Thank you to everyone in our community who assisted with this investigation and for your care and concern.
We ask that everyone keep the family in your thoughts and respect their privacy during this difficult time.”
Abosede was last spotted leaving her home west of Springbrook Golf Course for a morning walk.
Her husband, Gbenga Abosede, said surveillance footage captured her walking away from their neighbourhood.
She was seen at about 9:20 a.m. in the 2100 block of Sudbury Street, wearing a long-sleeved black Adidas jacket, gray sweatpants, a black headscarf, and black Crocs.
Police and volunteers, including canine teams, had been searching the forest preserve for weeks.
Our hearts go out to Sinmi’s family, friends, and loved ones during this incredibly difficult time,” Forest Preserve District Police Chief David Pederson added.
Investigators said there was no sign of foul play, though an autopsy will be conducted by the DuPage County Coroner’s Office.
