Clark Rockefeller back in court Friday

He got more gold coins returned, now Clark Rockefeller hopes a judge will allow him to present an insanity defense in the kidnapping of his daughter Reigh "Snooks" Boss, this past summer.

Rockefeller, aka Christian Karl Gerhartsreiter, aka Christopher Chichester, will make an appearance in Suffolk County Court Friday, according to Jake Wark, a spokesman for the Suffolk County District Attorney's office.

"It's a hearing on his potential use of an insanity defense," Wark said.

A doctor who examined Rockefeller's mental state will testify in court, officials said.

Rockefeller has been named as a person of interest in the 1985 disappearance of John and Linda Sohus, a San Marino couple. In 1994, bones were discovered in the backyard of the Sohuses home on Lorain Road. Those bones are believed to belong to John Sohus, although no positive identification has ever been made.
