From the link above, I thought what the mom had to say was interesting:
Ferrante also seems to has two older children.Lois Klein said she spoke on Thursday with a Pittsburgh police detective who questioned her about her daughter's marriage to Dr. Robert Ferrante, 64, including whether she wanted a second child. The couple have a daughter, Cianna, 6. Ferrante has two adult children. Autumn Klein was taking fertility drugs, officials said.
“She never liked being an only child,” Lois Klein said. “She didn't want her child to be an only child.”
Still, Lois Klein said she hadn't talked to her daughter recently about having another baby and was surprised Ferrante brought it up after his wife became sick.
“During the course of things, he told us they were trying to have another child,” Lois Klein said.
Autumn Klein, chief of women's neurology at UPMC, met Ferrante while she was a student working at the VA Hospital of Bedford, Mass. They shared a common interest in neurology, her mother said.
“She got kind of interested because of his brain, too,” Lois Klein said. “They could converse with one another very easily with no problems because they both understood what was going on. We thought he was a little too old for her, but we came around because he seemed to be the one she wanted.”
