CNN  — 

A 34-year-old mother of two has been found safe three weeks after she went missing while jogging in northern California, the Shasta County Sheriff’s Department said Thursday.

Papini was found in Yolo County, California, about 140 miles from the Mountain Gate trail where she was last seen.

Bosenko said Papini was spotted on the road by a driver about 4:30 a.m. Thursday.

“She is safe, in stable condition and receiving medical clearance at an undisclosed hospital,” he said. “She has been reunited with her husband.”

Authorities are looking for two women in a dark SUV in connection with the case, the sheriff added. They reportedly are armed.

Bosenko said Papini “was released by her captor on a rural road near I-5. … She was bound with restraints but was able to summon help from a passing motorist.”

An iPhone, a pair of earbuds and a few strands of what was believed to be her hair were the only leads discovered in the days after Papini went missing November 2. They were found on a jogging path not far from the Papinis home.

Last Wednesday, Papini went for a jog as usual, Bosenko said. Neighbors told authorities she was last seen in the mid- to late-morning or early afternoon. She wore a pink jogging top.

Later that day, her husband Keith arrived home and it was unusually quiet, he told CNN affiliate KRCR-TV.

“On normal days, I would open the door and my family comes, runs and give me a hug,” he told the station.

Papini was not home. Nor were the couple’s two children – ages 2 and 4. Her husband told the station that he called their day care center and learned the children hadn’t been picked up.

Keith Papini used an app to track down his wife’s smart phone, KRCR reported. It was down the street from their home, off Old Oregon Trail.

“Best mom I’ve ever seen”

Sheila Koester, Sherri’s older sister, told the station that Papini texted her husband that morning to see if he was coming home for lunch. He wrote back that he wasn’t.

Koester and Sherri’s sister-in-law, Suzanne Papini, both described the missing woman as a “supermom” who would not disrupt the routine of her children, according to KRCR.

“She is an incredible human being,” Suzanne Papini told the station. “Best mom I’ve ever seen.”

Authorities have used scent dogs and helicopters to search the area, Bosenko said. They have also been contacting registered sex offenders.

He hasn’t told the children their mother is missing, the station reported.
