KANSASVILLE -- The four-month long disappearance of Lynn Rickard has turned into a recovery effort.
The 59-year-old Kansasville mother who relies on an oxygen tank vanished from her home June 25 with no clothes on.
They hoped the fall conditions would make it easier to find her and bring closure to her devastated family.
The sheriff used drones and cadaver dogs out of Madison to find answers.
"They are the best of the best. We had them out here before and we had some hits that we're looking at now," said Sheriff Christopher Schmaling, Racine County.
Those hits brought them to bare footprints in the Summer they believe are Lynn's.
Her husband says Lynn who had medical issues escaped from their home with no clothes on.
The sheriff believes there is no reason there is any foul play.
The family has a $50,000 reward for her safe return.
