"Please come home. Please, we need you. Please ... I love you," said Egon Walters, Margot's husband.
Egon is desperate to find his wife of more than 50 years. He last saw Margot Friday around 1 a.m. as she slept in their bed. Egon says he got up to take a sleeping pill, and when he awoke a few hours later, she was gone.
"Early in the morning, I heard something. And, I came out and seen my dad frantic, saying, 'Mom's gone,'" said Michael Walters, Margot and Egon's son. "I said, 'What do you mean Mom's gone?'"
Margot left behind her purse, I.D., cell phone and house and car keys. She was also not wearing shoes. She was last seen in her pajamas and slippers. Her husband admits they had a small verbal fight the night before and initially thought she left to take a walk. However, five days have passed with no sign of her.
"If somebody picked her up, please call ... We want to know where you are," said Egon. "We're all sorry [for] what we did to you. Please call."
When asked why Egon was sorry, he said he was apologizing for an argument, nothing major. When Eyewitness News asked if he ever harmed his wife, Egon said he never touched her or harmed her in any way.
Authorities have searched the area, including the trails near their Aliso Viejo home.
"It's been five days. So as more time passes, of course the concern grows," said Jim Amormino, Orange County Sheriff's Department.
Margot has two grown children and one grandchild. Her husband says she does not suffer from dementia, but does have high blood pressure. Margot is 5'6" and 133 pounds.
"Please let us know. Even if you want to come back. Please call somebody so we know you're still alive," said Egon.
If you have seen Margot Walters, you are asked to call the Orange County Sheriff's Department at (714) 628-7170.
Searchers are expected resume the search after 6 p.m. on Wednesday.
