Former Playboy centerfold apparently jumps to death with son
"Adams was Playboy’s Miss November centerfold in 1992. The New York Post profiled Adams in 2013, saying that she had by then written more than 25 self-help books, ran an online beauty products company and managed the finances in her husband’s office. She appeared again in Playboy in 2003, and she had also worked with Elite Model Management and had two business degrees, according to the Post profile."
"Felder said he had been friends with Adams for 20 years but stopped representing her in the divorce case a couple of months ago. Recently, she had been hoping to go to Europe to be with a boyfriend there, and that had become an issue in the case, he said.
"She was never depressed while I knew her. She had certain problems, but depression wasn’t one of them,” Felder said."
