STAMFORD, Conn. (AP) - The mother of Connecticut school shooter Adam Lanza told a divorce mediator in 2009 that she didn't like to leave him alone and that she would care for him as long as he needed it.
When Lanza's parents divorced in 2009, the settlement left his mother with a comfortable income and the comfort of knowing that the then-17-year-old boy would have his education paid for and his medical insurance covered.
If there was bitterness and anger between Nancy and Peter Lanza, it is not described in court papers. And there was no mention of any lingering mental health or medical issues for Adam Lanza, nothing that could even hint at the horror he would unleash three years later.
In working through the terms of their divorce, the couple spent considerable time talking about how to provide for Adam Lanza's well-being, said Paula Levy, a mediator who worked with the couple.
During their meetings, the couple mentioned that Adam Lanza had been diagnosed with Asperger's syndrome, an autism-like disorder, Levy said. But the Lanzas were in complete agreement on how to address Adam's needs and said little about the details of his condition, Levy said.
"The only two things I remember them saying is that she really didn't like to leave him alone and I know they went out of their way to accommodate him," said Levy, who recalled Nancy and Peter Lanza as very respectful of each other and equally concerned about their son's needs.
"They worked together about it," Levy said. "The mom, Nancy, pretty much said she was going to take care of him (Adam) and be there as much as he needed her, even long-term."
Adam Lanza shot his mother in the head with a rifle Friday, then headed to Sandy Hook Elementary School armed with her high-power rifle, two handguns and enough ammunition to kill nearly every child in the building, authorities said. He killed 20 students and six adults before police arrived and he shot himself.
The Lanzas married in June 1981 in Kingston, N.H. Nancy Lanza filed for divorce in 2009, by then living with her son in the home where she was found dead in her pajamas, on her bed.
The documents suggest little argument. The couple agreed to split up their jewelry, clothes and family photos. Adam would live with his mother, the couple agreed, and they agreed to talk about the important decisions.
If it turned out they couldn't agree on something related to Adam's upbringing, Nancy Lanza "shall make the final decision," according to the Sept. 24, 2009, settlement approved by Judge Stanley Novak.
While she would not disclose details of their discussions, Levy wanted to make clear that the Lanzas were loving parents who wanted the best for their son.
"These people are soft-spoken, gentle, both of them saying, 'What can we do to help him?'" Levy said.
There is nothing in the divorce court file that discusses the relationship's underlying problems. The file simply says the marriage "has broken down irretrievably and there is no possibility of getting back together."
Nancy Lanza, received $289,800 in alimony this year. It was to continue until December 2023, with slight increases each year for cost of living.
As part of the divorce, both Nancy and Peter Lanza were ordered to attend a parenting education program, standard practice in Connecticut. The provider, Family Centers Inc., certified that both completed the required sessions.
Authorities pored over computer, cellphone and credit card records trying to piece together the Lanza family's days leading up to the shooting. Peter Lanza, in a statement this weekend, said that like everyone else, he could not comprehend what had unfolded.
"We too are asking why," he said. "We have cooperated fully with law enforcement and will continue to do so. Like so many of you, we are saddened, but struggling to make sense of what has transpired."
Asperger's is a mild form of autism often characterized by social awkwardness. While people with the disorder can become frustrated more easily, there is no evidence of a link between Asperger's and violent behavior, experts say.
