Authorities say they arrested Luis Hernandez in the Bay Area city of Fairfield.
He's accused of being one of two men who forced Jessica Llamas into a car at gunpoint after trying to rob her and her friends back on Oct. 9.
Jessica was discovered in Merced County, where deputies say her kidnappers dropped her off in the middle of nowhere.
The car used in the kidnapping was later found abandoned in Solano County.
