RACINE COUNTY, Wis. (CBS 58) -- The daughter of a missing Racine County woman has hired a private investigator to help find her mom.

Lynn Rickard walked away from her home in 2017 and hasn't been seen since. 

Police say Rickard climbed out of a window naked and without her oxygen tank. 

Lynn's daughter, Laura, hopes the investigator can find her mom nearly three years later.

"I'm just trying to get the word out there as far as possible," Laura Koehn said. "She may have been picked up by somebody, so maybe helping getting the word out as far as possible will bring her home."

Deputies in Racine say there is no foul play in this case. 

Social media pages have been created to aid in the search. The Facebook, Twitter and Instagram accounts have information and pictures of Rickard. Anyone with information is asked to call police.
