MOSCOW (CBS SF/AP) — Russian news reports said searchers on Saturday found the body of UC Davis graduate Catherine Serou, who had gone missing for several days in Nizhny Novgorod after texting her mother that she was “in a car with a stranger.”

Serou earned a bachelor’s degree in design and a master’s degree in art history at the UC-Davis before heading to Russia to further her studies.

Serou was last seen on Tuesday after getting into a car. In an interview with NPR, Serou’s mother said she received a frightening text from her daughter.

“It says: ‘In a car with a stranger. I hope I’m not being abducted.’ And that’s the last thing she wrote,” Beccy Serou told NPR. “She’s out there in this forest, I think, relying on her wits — if she hasn’t been killed — to stay alive.”
