“Hide your husbands,” 45-year-old Beverly Rolston wrote on a series of photographs, which security footage shows her posting all over the Ohio store in November, according to WLWT.
Police say the photos were stuck up within view of children.
The Walmart employee says she used to be friends with Rolston.
Rolston said she believed her husband and the woman had been having an affair for about a year, authorities said. Her husband had reportedly confessed the infidelity to her.
Rolston has been charged with one count of pandering obscenities. She has pleaded not guilty and her court case is continuing.
