UPDATE: 21-Year-Old Who Vanished En Route to Oakland Has Been Found

UPDATED Jan. 1: A Pleasanton family that had been posting missing persons posters in their search for 21-year-old Elizabeth Wassei said they have located her but did not give any details about what happened in the three weeks since she borrowed a relative's car and disappeared.

Elizabeth Joy Wassei, an Amador Valley High graduate and Las Positas College student, borrowed the car to drive from her boyfriend's grandparents' home in Sonora to visit friends in Oakland on Dec. 7, according to her sister, Miriam Wassei of Pleasanton.

"She just never turned up," Miriam Wassei told Patch Saturday. "She dropped off the map."

Miriam Wassei said it was unlike her sister to not contact her family at Christmas.

"She's never not called somebody, especially during the holidays. We have a big family and we're really close," Miriam Wassei said.

The family reported her missing on Dec. 23. She apparently was located around Dec. 31.
