Hrones previously had said that his client had few distinguishable memories prior to 1993, shortly before he married Sandra Boss, a business executive with whom he would have a daughter. After their 2007 divorce, Boss received "primary residential custody" of the child. Rockefeller was allowed to see his daughter under the condition that a social worker supervised the visits. It was during one of these visits in Boston on July 27 when Rockefeller allegedly executed the first part of his kidnap plan.
Rockefeller was arrested a week after the alleged abduction in Baltimore, where he kept a 26-foot catamaran and had purchased an apartment with the apparent intention of starting a new life with his daughter.
Hrones continues to challenge the charges Rockefeller faces in Boston. He said that, because there is no wedding certificate to document the Rockefeller-Boss marriage, there should not have been a legal divorce. Hrones continued to paint his client as a doting father who did nothing illegal when he took off with the couple's daughter, nicknamed "Snooks."
"According to authorities, he was never married, so how can you get divorced if he was never married?" Hrones said.
Rockefeller will not cooperate with investigators, Hrones said, adding that his client has been given articles about the case from American and European media outlets. Rockefeller also asked his attorney to bring him a "Star Trek" book to read in jail.
Authorities unraveling Rockefeller's back story believe he apparently arrived in Berlin, Conn., from Germany for an exchange program in 1978 under the name Christian Gerhartsreiter, police sources say.
A childhood friend in Bergen, Germany, the small German community where Gerhartsreiter grew up, described the former classmate to ABC News as bright and clever, but also as a spoiled loner who could have a violent temper. It came as no shock that Gerhartsreiter may be living in the United States under several aliases.
It came to light Friday morning that Rockefeller's birth brother was located in Bergen, Germany, according to separate reports published in the Boston Globe and Boston Herald.
When shown several pictures of Rockefeller that have circulated since the child's alleged abduction sparked an international manhunt, a man identified as Alexander Gerhartsreiter said that he was shocked to learn that his brother had been found.
Gerhartsreiter said that his brother, Christian Gerhartsreiter, was born in Siegsdorf and raised in the same house in Bergen, where their mother continues to live today. He left for an exchange program at a Connecticut high school in 1978.
Gerhartsreiter said that before he cut off all communication with his family in 1986, his older brother told the family that he had changed his name to Christopher Chichester, the Herald reported.
ABC News' attempts to contact Alexander Gerhartsreiter and his mother during the weekend were unsuccessful.
A neighbor, Helga Hallweger, told ABC News that Christian and Alexander Gerhartsreiter's mother is a recluse, and that Christian did not make much of an impression on her during his youth.
She described Alexander as a nice man, and recalled that he did major research a few years ago in an unsuccessful attempt to track down his brother in the United States.
