On Aug. 8, 2025, the family of Sinmi Abosede released a statement asking the community to continue their vigilance and call in any genuine tips that might help locate their beloved Sinmi, a 46-year-old Naperville resident who has been missing since July 30. Here is a recording of that statement, which is followed by a brief update from our department.

NEWS RELEASE: 

On Monday, Aug. 4, Naperville Police conducted a systematic search of Springbrook Prairie Forest Preserve in an effort to locate Olasinmibo “Sinmi” Abosede, 46, of Naperville, who was reported missing on Wednesday, July 30.

The search was conducted with the assistance of the Naperville Emergency Management Agency (NEMA) and area law enforcement. More than 40 trained volunteers, eight K9 teams, and multiple experienced police drone operators participated in the search. While today’s search did not lead officials to Abosede’s whereabouts, the Naperville Police Department’s efforts to locate Abosede will continue.

Detectives have been following up on leads, searching the area, and investigating Abosede’s whereabouts since she was reported missing by family on Wednesday.

Abosede was last seen at approximately 9:20 a.m. on July 30 walking away from her home on the 2100 block of Sudbury Street in Naperville. She is described as a black female with black hair and brown eyes, standing 5 foot 6 inches tall and weighing 190 pounds. Abosede was last seen wearing a long-sleeved black Adidas jacket, grey sweatpants, a black head scarf, and black Crocs. She was carrying a white water bottle, and apparently left her cell phone, credit cards and other personal items behind.

Foul play is not suspected in her disappearance.

“I understand that the uncertainty surrounding Sinmi’s disappearance is concerning, and I assure you that this department is doing everything we can to find Sinmi,” said Police Chief Jason Arres. “We will continue to follow up on any leads and lean on the expertise of our partners at NEMA and surrounding law enforcement agencies, who I want to thank for their dedicated efforts today.

“We know there are a lot of community members who want to help, too,” Chief Arres continued. “I would ask that they continue to circulate Sinmi’s picture and keep their eyes open as they travel throughout the region. The more eyes we have looking out for her, the better.”

If you see Abosede, please call 9-1-1 immediately to report her location. Anyone with information regarding her disappearance is asked to call the Naperville Police Investigation’s Division at 630-548-1421.

The Naperville Police Department will communicate any major developments in this case but does not intend to provide regular updates on the status of the investigation.
