Police Monday were asking the public to help them locate a Manhattan Beach woman who disappeared from the Los Angeles County Museum of Art.
Nancy Paulikas, 55, was last seen at about 3 p.m. Saturday at the art museum at 5905 Wilshire Blvd., police said.
Paulikas suffers from dementia, authorities said.
Paulikas and her husband were at the LACMA when family members went to the restroom. When her husband returned from the restroom, Paulikas was gone, he said.
Museum staff swept the grounds and did not find Paulikas.
"It's heartbreaking," said Matthew Lewis, a family friend. "The fact that we don't know where she is spending the nights -- we don't know where she is during the day, how she's feeding herself. It's the nightmare scenario."
Her husband has been passing out fliers since Sunday.
She is described as 5 feet 7 inches tall, about 140 pounds, with brown-gray hair and blue eyes. She last was seen wearing a red long-sleeve blouse with a white paisley-flower pattern, blue jeans and black and white sneakers. She was also wearing a metal medical alert bracelet that says "My name is Nancy, and I have dementia."
Anyone with information on Paulikas' whereabouts was asked to call the Los Angeles Police Department Wilshire Station at (213) 473-0476.
