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.
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.
