LONDON — A missing 96-year-old woman from the small Freeborn County community of London was found alive Friday afternoon after a search involving nine different agencies and a handful of volunteers.

A Minnesota State Patrol helicopter crew member found Rose Foss lying in a cornfield north of her home, just south of 120th Street in London, shortly before 4 p.m.

According to a news release, Freeborn County Sheriff’s Office deputies were dispatched to London at 10:01 a.m. Friday for a complaint that Foss was missing.

Freeborn County Sheriff Kurt Freitag said Foss’s last known contactwith someone else was at 11 a.m. Thursday. It is unclear how many hours she had been in the cornfield, and authorities are investigating how she ended up there.

After receiving the call Friday morning, deputies arrived at Foss’s house in London and conducted an initial search. When they were not able to find her, they quickly paged area fire departments to bring in more search and rescue personnel, the release stated.

The Freeborn County Sheriff’s Office was assisted at the scene by Freeborn County Emergency Management; the London, Myrtle, Hayward and Glenville fire departments; Gold Cross Ambulance; the Minnesota State Patrol; the Worth County Sheriff’s Office K-9 unit; and a handful of volunteers.

Once the helicopter arrived on scene, searchers on foot were pulled into a central location while the helicopter crew conducted a grid search of the area, which consisted of a wooded area and cornfields.

At 3:51 p.m. a crew member on board the helicopter found Foss and stated she waved at him.

A deputy went to Foss’s side, where she was in a muddy puddle. The deputy assisted her until medical personnel arrived on scene.

She was transported by ambulance to Mayo Clinic Health System in Albert Lea for observation.

Freitag thanked everyone involved for their efforts.

The first responders and volunteers were relieved Foss was found.

“It’s wonderful,” said Reuben Unseth, her pastor at Calvary Lutheran Church. “It’s an answer to our prayers, and I thank the Lord we found her alive. It was a great effort by everyone.”
