Claudia is missing with her daughter, Claudia "Jareth" Guillen. They were last seen together at a store in Yuma, Arizona on November 24, 2004. Neither of them have been heard from again. Claudia had been driving her grandmother's car that day, and it was found abandoned in front of the store. Her grandmother reported the disappearances to the police after she found out her car had been towed.

Authorities suspect foul play was involved in the mother and daughter's disappearances. Ricardo Salgado, Claudia's boyfriend, has a history of domestic violence and is considered a person of interest in the case. He went to Mexico after he was initially interviewed by police. Mexican authorities tracked him down and questioned him again, but he didn't provide any useful information. Claudia and Jareth's disappearances remain unsolved. They may be in Mexico.
