A $10,000 reward is now being offered for the return of a Racine County woman missing since Sunday.
Lynn Rickard, 59, walked away from her home in Kansasville and authorities say very few tips have come in regarding her disappearance.
The search has expanded Tuesday into Kenosha County. According to Racine County Sheriff Christopher Schmaling, the last time Rickard walked away from her home, she mentioned wanting to go to Kenosha to see her doctor.
But Lynn's husband John Rickard now thinks someone may have picked her up.
"It seems as though the trail has gone cold," John said.
John says he feels helpless sitting at home but he knows authorities are undergoing a massive search for his wife. He is offering the reward hoping it leads to information.
"She kissed me goodnight, said 'I love you, sweet dreams' and I said the same," John said. "That's the last I [saw] her."
He says three weeks ago, his wife Lynn managed to walk about five miles away from their home. But that time, he said she was fully clothed and wearing shoes.
On Sunday morning, John says his wife climbed out of a window, leaving her clothes and her oxygen behind.
"She wanted to be free from her oxygen, she felt self-conscious," John said.
Schamling says his deputies worked overnight using thermal imaging cameras and Tuesday morning, moved into Kenosha County, using drones to search the area from the sky.
He says there is nothing at this point to suggest foul play.
"I've personally spoke with her husband, I've been in their home, I've seen how she left in the past," Schmaling said. "She's had a history of doing this as well. There's nothing to report otherwise, other than her walking away being confused, scared."
Schmaling says because of how rural the area is near the Rickard's home, he is urging people in the area and in Kenosha County to check any hiding places on their properties.
Anyone who sees Lynn should call 911 immediately. If you have information about her disappearance, you're asked to call the Racine County Sheriff's Office at 262-886-2300.
