"We currently have no reason to disbelieve Sherri Papini's story, Shasta County Sheriff Tom Bosenko said on Sunday. "She was assaulted and had injuries which she was treated for."
The Sheriff also said that investigators are looking into past incidents with Sherri Papini and are aware of her previous marriage and divorce and are checking into her past, including any online activity.
Investigators put out 20 warrants for data including surveillance cameras and cell towers. The camera footage, from locations in Yolo County and the city of Redding, include homes, business, a church, motels and traffic cameras.
Police are also sifting through cell tower information from the area where she was dropped.
Papini was reported missing on Nov. 2 after she went for a run and didn’t return home. The mother of two young children, Papini was described by her family as a "super mom."
Papini's cellphone, earbuds and a strands of her hair were found along a rural road, raising fears of foul play.
She was found three weeks later on Interstate 5 in Northern Yolo county.
The sheriff said that the case is still an active investigation and that authorities are “looking for a dark-colored SUV with two Hispanic females armed with a handgun.”
