Thursday, the Justice Department announced the arrest of 39-year-old Sherri Papini on charges of making false statements to a federal law enforcement officer and engaging in mail fraud.
Papini went missing while jogging in November of 2016.
She was found 22 days later along I-5 in Yolo County.
She told police that two women kidnapped her at gunpoint.
Authorities say they've now determined that Papini made it up, injured herself as a cover story -- and was actually staying with an ex-boyfriend in Southern California while she was missing.
If convicted, Papini faces five years in prison and a $250,000 dollar fine.
