Clark Rockefeller with daughter Reigh
The man known in Massachusetts as alleged kidnapper Clark Rockefeller has been identified as a person of interest in a double-homicide in California, authorities said Friday.
Rockefeller's real name is Christian Karl Gerhartsreiter, who was born in 1961 in what was then West Germany, according to a joint statement by the FBI, the Suffolk County (Mass.) District Attorney, the Boston Police Department and the Massachusetts State Police.
They say they tentatively determined his identity before they arrested him on suspicion of kidnapping his daughter on July 27, after they compared his fingerprints on a wine glass in Boston to, among other things, a decades-old immigration file.
A more definitive identification, using forensics, was made Thursday at the FBI's laboratories in Quantico, Va.
The FBI alleges that Gerhartsreiter used the alias Christopher Chichester when he was renting a guesthouse in San Marino, Calif., in the mid-1980s.
John and Linda Sohus, who lived in the main house, disappeared during that period. Police had long considered Chichester a "person of interest" in the disappearance.
Remains believed to be those of John Sohus were found buried in the backyard in 1994. Linda's remains have not been found.
Earlier this month, the man then calling himself Rockefeller was arrested in the kidnapping of his 7-year-old daughter, following an emotional videotaped plea
by the girl's mother for her return.
