During her testimony on Boss said her then- husband had described a youth growing up on Manhattan's exclusive Sutton Place, being home schooled, entering Yale at the age of 14, and how his parents died in a car crash.
She also said that he had claimed that an accident when he was 2 or 3 caused him to be mute. Boss elaborated on that today, recounting that Gerhartsreiter told her that he was mute for eight years until he saw a dog and yelped, "Woofness," and began to speak again.
A different portrait emerged, however, from Rockefeller's friend Don Fox. Fox's daughter was a classmate of Reigh's, and the fathers became friends.
Fox described Boss as a cold and distant mother while Rockefeller was with his daughter constantly.
Parents at the school "never saw Sandy," Fox said.
"She was never around. Even on the weekends she would go shopping in New York," Fox said. "She was always absent. She made Clark do everything for her. It was always Clark and Reigh. She is not a very caring or giving person. She is very cold and aloof."
During testimony on Monday, the man who was recruited to drive the getaway car when Gerhartsreiter allegedly kidnapped his daughter said he practiced the kidnapping by hurling duffle bags into the back of a livery vehicle the day before he snatched her off a Boston street.
Darryl Hopkins, the wheelman on that July day when Reigh was thrown into a waiting black suburban by her father, said Gerhartsreiter paid him $3,000 to "get rid of" the "cling-on" following the dad-daughter visit.
The person Gerhartsreiter claimed was a "cling-on," or unwanted friend, was a social worker appointed by the court to supervise Gerhartsreiter's visits with his 7-year-old daughter.
Hopkins said Gerhartsreiter tossed his daughter into the car, banging her head on the door, and shoved the social worker to the ground.
"Snooks was crying. She was saying, 'I really whacked my head, Daddy.' Clark was saying: Go! Go! Go!'" Hopkins testified.
Hopkins peeled away from Marlboro Street and testified that social worker Harold Jaffe desperately clung to a door handle.
"I could feel him pulling on the door," Hopkins said. "Clark was holding the door shut."
Hopkins said that Gerhartsreiter had asked him for a ride to Newport, R.I., to "hobnob" with Sen. Lincoln Chafee, a former Republican senator from Rhode Island.
"They were going sailing with the senator's family," Hopkins said, although there is no evidence that he had an appointment with the former senator.
The driver ridiculed Rockefeller for talking like "Thurston Howell the third," the aristocratic character on the old TV show "Gilligan's Island."
On an previous trip, Hopkins complained that Rockefeller had stopped at a Manhattan bar to eat a rich meal and didn't buy his driver anything.
"He had steak tartare," Hopkins told the court, mimicking a Thurston Howell III voice. "I was his driver. He should have bought me a sandwich"
