A search for a missing Racine County woman is entering its second night.

Lynn Rickard walked away from her Kansasville home early Sunday morning. The 59-year-old suffers from a mental illness and is oxygen dependent.

The Kansasville Fire department is the headquarters for the search, which spans miles around the area.

“I’m just praying for a miracle,” said John Rickard, Lynn’s husband.

It’s been more than 36 hours since John saw his wife of 22-years. He says she suffers from an illness and after a recent medication change, she started wandering away.

“She tried to leave a few times and I put alarms on the door and triple locked,” John said. “This time she went out the window.”

Lynn, who is about 5’4”, 150 lbs with brown hair, left home naked and without her oxygen tank, which she relies on.

“From farm fields to pole barns, underneath porches, we are literally looking everywhere,” said Racine County Sheriff Christopher Schmaling.

The Racine county sheriff’s department along with several area fire departments are scouring the area using ATVs, while the civil air patrol search the area from the sky.

“The last time she walked away, she was about four miles away so, we extended our search,” Sheriff Schmaling said.

The sheriff is also asking anyone in the area to check the yards, barns and sheds.

“We’re remaining positive, as positive as we can be, given the circumstances and how many hours have passed,” Sheriff Schmaling said.

And even as the hours click by, Lynn’s family remains hopeful.

“I love her,” John said. “I miss her very much.”

Crews will continue the search through the night and in to Tuesday if needed.
