Chicago police said the report was "unfounded" and, according to a statement from officials, "Detectives confronted the victim with inconsistencies between her account of the incident and recovered video, and learned that the story was not true."
Through her door, the 68-year-old woman spoke with ABC7 News.
"I found the jewelry and I must've been very confused. And I'm on medication and something must've triggered this. I must've seen something that triggered this on the Avenue, and I must have gotten frightened. That's all I can say," she said.
On Thursday, she had said she was mugged by a group of young men on Wednesday around 12 p.m. near Saks Fifth Avenue. She told security they took $135,000 worth of jewelry.
Officials said in a statement that detectives will determine if charges are "prudent and would serve a police purpose."
