Audrey Backeberg was 20, living in Reedsburg, Wisconsin, when she disappeared in July 1962. A renewed investigation resulted in quite a surprise. She was still alive — and went missing on purpose.

The Sauk County Sheriff's Office announced the resolution of the cold case in a news release last week, explaining that Audrey Backeberg disappeared of her own free will.

On the morning of July 7, 1962, Backeberg left her family’s home to go pick up a paycheck at the local woolen mill. Backeberg never returned home, prompting her husband, Ronald, to contact her relatives to inquire about her whereabouts, but she was not subsequently seen for decades.
