Early indications were that Sherri Papini had been released by her captors, Shasta County Sheriff Tom Bosenko said at a news conference.
"She was bound with restraints but was able to summon help from a passing motorist", he told reporters Thursday.
Asked about it, Bosenko said the website played no role in Papini's release.
So far, the investigation points to what happened to Papini being an isolated incident, he said. He also said no motive for the abduction has been uncovered.
Bosenko said there was "sensitive information" related to the disappearance that he would not disclose.
Papini was released early Thursday morning by her captor or captors on a rural road in Yolo County, about 150 miles from her home, Bosenko said.
"Obviously she was emotional and quite upset, but elated to be freed, and so we were able to get some information from her", he added.

Sherri has been reunited with her husband, Keith.
Phone numbers for Papini and some of her family rang through Friday, and the Shasta County sheriff's office did not immediately respond to calls, messages and emails seeking comment.
Her husband Keith reported her missing after she failed to collect their two young children from day care at the beginning of November.
A private group working with Papini's family released a video Wednesday offering $100,000 to anyone with information leading to her safe return, according to NBC affiliate KNVN. "Although I have no details yet we are joyous that Sherri is alive and Keith is reunited with her in the hospital".
Using the Find My iPhone app, he found her cell phone and ear buds about a mile from their home.
Koester could not give an answer on whether or not Sherri had been reunited with her kids, but she did reiterate that Sherri was very excited to be home and back with her family.

Papini also may have undergone sheer terror from being away from her husband and kids for so long.
