A large police presence was seen in the area of the forest preserve Thursday. Chopper 7 was over the scene as police blocked off a grassy area.

A body found Thursday has not been officially identified as Abosede, police said.

The DuPage County coroner has scheduled an autopsy for Friday.

There has been an ongoing large-scale search for the missing woman in the past three weeks.

The Forest Preserve District of DuPage County said on social media they were helping Naperville police in the search at Springbrook Prairie Forest Preserve on 83rd Street, about 1.5 miles from the woman’s home.

Abosede, a mother of four, was last seen July 30 on the corner of Sudbury Street and Lindsay Drive, near her home, at 9:20 a.m.

Dozens of volunteers were helping, along with K-9 teams and drones.

Abosede has a condition that places her in danger, police said. She was carrying a white water bottle and apparently left her phone, credit cards and other personal items behind.

Naperville police said the thick growth and terrain of the preserve has made their search challenging. Springbrook Prairie is nearly 2,000 acres.

Naperville police have released few additional details about their investigation. At this point, they maintain that foul play is not suspected in her disappearance.
