Local police in Northern California were searching Monday for Sherri Papini, a 34-year-old mother of two, who was reported missing by her husband last Wednesday when he arrived home to find that their children hadn’t been picked up from day care. 

Papini, was last seen jogging by herself and wearing a pink running jacket on the street. Her husband, Keith Papini, said that was something she did almost every day, according to local reports. Sherri Papini was described as 5’4” and 100 pounds with blonde hair and blue eyes.

After finding his house empty upon returning from work, Keith Sabini used his “Find iPhone” app to locate Sherri’s phone. He said he found Sherri’s mobile phone on the side of the road, but she was nowhere to be found. His wife had texted him earlier that day.

He proceeded to report his wife missing. “Knowing that she didn’t pick up our kid… there is no way that ever happens,” Keith Papini told ABC News Sunday. “She could drop her phone, but she would never in a million years not pick up our children on a time that she normally would have.”

Family members said Sherri was likely abducted. “Everybody who knows my wife knows that there’s no reason for her to leave… She was definitely taken against her will,” said Keith Papini

Shasta County Sheriff Tom Bosenko said his department had yet to identify anyone involved in her disappearance. Officials were investigating four registered sex offenders in the area, the Ventura County Star reported.

“The Sheriff’s Office is aware of the multiple theories about what may have happened with Sherri Papini,” Jgt. Brian Jackson of the Shasta County Sheriff’s Office said. “The Sheriff’s Office encourages the public to continue to be supportive to family as well as law enforcement efforts as these are stressful circumstances.”

“She wouldn’t just drop her phone if she was running away,” Suzanne Papini, Keith Papini’s sister, told the New York Daily News.

Papini’s family has offered a $50,000 reward to anyone who has any information on her possible whereabouts.
