No, no lawyer was in the house when JonBenet's body was found.
John had already treated her as though she were invisible. He and Patsy were too good to talk to blue-collar police officers. They'd hire their own army of cops, John said. He actually wanted to hire the Russian Army and seal off the city.
That's how "out in the ether" they were at the time in their "money can buy anything" little world of megalomania they lived in. Not everyone who has a lot of money thinks or acts that way.
Does John still live in Atlanta?
