Southeastern Michigan authorities are closing an investigation of an 18-year-old woman's claim she was abducted along a road and held hostage for 16 hours, saying it never happened. The Monroe County sheriff's department says a detective and an FBI agent re-interviewed Hayley Turner Sunday and "determined that the incident did not take place."

The department says it's forwarding a report to the county prosecutor's office for review.

Turner allegedly left her home on Thursday evening to run an errand, and shortly after told a friend over the phone she was pulling over her vehicle to check on a man who was lying in a ditch, Monroe County Sheriff Dale Malone said during a morning news conference Friday. "Seconds later, Hayley told her friend, 'he has a gun,'" and the call was disconnected. Turner was found on a porch about 45 miles from where she allegedly vanished, according to NBC affiliate WDIV. On Friday, Turner's family told the station the woman is fine physically, but had struggled with some emotional issues this year.
