Grand jury investigates missing San Marino couple
A Los Angeles County grand jury is examining evidence in the 1985 disappearance of a San Marino couple who rented a guesthouse to a man now considered a person of interest in the case, according to two handwriting experts who have received subpoenas.
The man, whose real name is Christian Karl Gerhartsreiter, was arrested last summer in Boston under the name Clark Rockefeller on suspicion of kidnapping his daughter. He has become the focus of a probe into the disappearance of Jonathan and Linda Sohus. It's unclear what happened to the couple, but authorities twice have dug up the backyard of the house, searching for their bodies.
Rockefeller has denied any involvement in the disappearance.
The German immigrant left San Marino after the couple vanished. They later sent a handwritten postcard from Paris. Katherine Koppenhaver and Sheila Lowe, handwriting experts, said the district attorney’s office recently presented them with grand jury subpoenas for all their reports and handwriting samples in connection with their examination of that postcard and other evidence in the case.
A district attorney’s office spokesman declined to confirm any grand jury proceedings, noting that they are secret.
