Police officers working the Sherri Papini kidnapping case may have had a lead in the mysterious November disappearance of the stay-at-home mom — and it may have been in Michigan, according to an exclusive Sacramento Bee report out Monday.

Authorities in Shasta County, California, where Papini vanished Nov. 2 while on a run, have more or less stopped providing updates to the public ever since the 34-year-old returned Thanksgiving Day. Citing the ongoing probe into her case, the sheriff's office has refused to give details or grant several public records requests from the Bee. But recently obtained expense reports from Nov. 9 through Nov. 11 indicate that detectives went to Detroit, Canton, New Hudson, Northville and Plymouth, Michigan.

Sheriff Tom Bosenko would not tell the Bee why the officers traveled there or whether they turned up any results. However, he did say the Papini case remained a priority. Answers could come soon.

"You never know on these cases," he added.

Papini and her relatives, many of whom were vocal and gave press interviews while she was missing last year, have stepped out of the spotlight since she was found, wearing restraints and beaten, on the side of a road about 140 miles away from her house in Redding. Papini, her husband, Keith, and her children reportedly left home for a stay "up north" after the kidnapping. They also appeared in a series of New York Post photos Jan. 4.

However, they have not commented to the press except to request time to heal.

"I can't speak to more recently, but even initially we had asked Mr. Papini to refrain from media interaction and especially after she was found, with some of the information he was releasing," Bosenko told the Redding Record Searchlight earlier this month.

Before she went incognito, Papini described her alleged abductors to police as two Hispanic women with a gun. Composite illustrations of the suspects have not yet been released.
