As authorities begin to put the pieces as to what led to gunman Adam Lanza to take the life of his mother Nancy and that of 26 other individuals as well as himself investigators have come to learn that 3 days prior to his murdering spree the young man had had an altercation with his mother that had left him venting.
At the time Nancy Lanza had become increasingly concerned about her son’s inability or lack of desire to get out of the house and essentially live a withdrawn existence where he spent most of his days playing violent video games in a windowless basement room.
She had wanted him to apply to college, to finally begin to think about life outside of the house but the young man had become increasingly hostile to the idea, choosing instead to withdraw in the sanctity of his violent make believe world.
Nevertheless Nancy Lanza opted to go on a 3 day vacation on her own (Bretton Woods in New Hampshire, where she habitually liked to go) leaving her son to vent and plot his murdering spree whilst she left him all alone in the house. It may have appeared to the young man that his mother’s desire to have him leave the house was the final nail in the coffin of being ostracized (in his mind) after being alienated by his father, Peter and brother Ryan who he had by now had very limited if at all engagement with in the last few years.
During the three day absence the young man had cut off all communications with his mother and set about getting revenge for the hurt that he was now feeling. It is also believed that in the end the young man targeted the elementary school down the road because in his mind Adam Lanza had come to believe his mother left the children there more than him. Other notions also include wishing to inflict as much pain to the outside world as he believed had been inflicted on him.
