There's another bizarre clue in the Sherri Papini case that has investigators baffled.

The case of missing Californian jogger Sherri Papini has both authorities and the public desperately searching for clues as to what exactly happened to the mother-of-two after she was allegedly kidnapped one month ago.

Papini, 34, was thought to have disappeared while out for a jog on November 2 and was not seen again for 22 days when she was found badly beaten on the side of a rural road.

Another bizarre twist in the case, however, has police concerned one of their key pieces of evidence may have been planted.

Just days after the so called "super mom" vanished her iPhone and headphones were found on the Mountain Goat jogging trail, just a few kilometres from the Papini's home in Redding, California.

Yesterday's report: Police share even more disturbing facts about Sherri Papini after her husband "blindsided" them.

They were found by Sherri's husband, Keith Papini, using the “Find my iPhone” app with several of her long blonde hair were tangled in the cords.

Shasta County Police Sheriff Tom Bosenko today confirmed a rumour that the smartphone may have been a 'red herring' that was "neatly placed" in the woods - rather than lost in a struggle - to throw them off.

"It appeared they had been set in some grass with the screen facing up, and then the earbuds to the phone were loosely coiled and appeared to be placed on the screen," he told America's Today program.

The revelation raises a number of possibilities including that Sherri may have been taken from somewhere other than the track, possibly by someone known to her.

This adds to a number of unconfirmed reports half-wrapped Christmas present was found at her home, suggesting she may have been snatched from there.

Sheriff Bosenko also said "a number of evidence items” from the roadside area where Sherri was found, bound and battered.

One is believed to be a bag placed over her head, which she managed to take off to flag down a passing car whose driver called 911, despite not stopping.

Sherri has claimed her captors were two Hispanic women armed with a handgun, one  “younger”, with long curly hair, thin eyebrows, pierced ears and a thick Spanish accent.

The other with straight black and grey hair and thick eyebrows, according to News.com.au.

The statistical unlikelihood of such a pairing  has added to speculation the story may have been fabricated to incite a 'race war' or cover the tracks of another perpetrator.

Police were forced to reveal a number of other disturbing details about Sherri's condition after Keith gave an exclusive interview to America's ABC News without their consent and released a detailed statement to Good Morning America.

"She was bound, she had a chain around her waist, that is correct, she had a bag over her head, that is correct," he told ABC News of the moment his wife was found.

"Her left hand was in the vehicle chained to something, she was chained anytime she was in a vehicle. They opened the door, she doesn’t know because she had a bag over her head, they cut something to free her restraint that was holding her into the vehicle and then, kind of, pushed her out of the vehicle."

In his statement Keith also revealed Sherri had been "branded" with police later confirming the marks contained "a message".
