RIVERSIDE, Ohio (WDTN) — The Montgomery County Coroner confirmed Tuesday that a 27-year-old woman who was considered “missing under suspicious circumstances” was found dead in Dayton.

Brooke McCullough, of Huber Heights, was last seen by her father Sunday, July 18, around 10:45 a.m. leaving the Christy Club in Riverside. She was picked up in a dark colored Dodge minivan or Chrysler Town & Country.

Using an app on her phone, authorities have determined that from Sunday morning until Monday morning the phone was in West Dayton, Trotwood, North Dayton and Harrison Township. The phone shut off a little before 10 a.m. Monday morning.

She has since missed work, a “no call no show,” which is out of character for her, according to family.

McCullough’s death was pronounced July 21 but the cause and manner of her death have not been determined. Her death is being investigated by the Dayton Police Department.
