But the Shasta County Sheriff's Office said her claims don't add up to a consistent narrative.

Authorities have found that Papini actually had male DNA — determined not to be from her husband Keith — on her clothes when she was picked up by the police, even though she said two women abducted her. A woman’s DNA was also found on her body.
Papini also told police that at one point she fought back against one of her captors and cut her foot, but authorities said they found no evidence supporting that claim.
"When she was being processed at the hospital … no evidence of a cut was seen in the photographs," Sgt. Brian Jackson told Redding's Record Searchlight newspaper.
Jackson said police investigated Papini's alleged relationship with a "male acquaintance from Michigan," thinking it might be related to the case. According to police, the man was in California on business a few days before Papini's disappearance, and she had planned to meet him. However, police eventually concluded the man had nothing to do with the case.
According to the Record Searchlight, Jackson said authorities examined other cases involving abductions and human trafficking that some news outlets had compared to Papini’s disappearance, but nothing like Papini’s case turned up.

"There have been no cases discovered that are similar in nature to this investigation concerning the pattern of operations by the suspect[s], treatment of the captured victim and release of the captured victim," Jackson said.
