Sandy Hook gunman Adam Lanza was left home alone with an arsenal of weapons in the $1.4million mansion he lived in with his mother for three days while she went on vacation, it emerged today.
During this time he refused to speak to Nancy and sources believe he may have become so consumed with anger, that it drove him to plan one of America's worst school shootings.
Before the deranged 20-year-old shot dead 20 innocent children and six brave adults who tried to stop him at Sandy Hook Elementary School last Friday, he shot his mom in the face four times while she lay sleeping in her bed.
The pair had not spoken for the whole three days she was gone. Consequently, Nancy would pay with her life.
According to Headline News, Nancy Lanza had left Adam alone while she went on a mini-break to Bretton Woods in New Hampshire - something she often did.
She had just arrived home on Thursday evening.
A friend said she trusted her autistic son and thought it was OK to leave him home alone.
She didn't, however, want him to cook while she wasn't there so would prepare him meals and leave them for him to reheat.
The 52-year-old checked into the Omni Mount Washington Resort at 12:10pm on Tuesday, December 11, and checked out at 12:27pm on Thursday, according to HLN.
It is a five-hour drive between there and her Newtown home. She would always drive there, her friend said, and when she spoke with Nancy during her getaway she was in 'good spirits'.
According to the New York Daily News, Adam stopped speaking to his mother because she was trying to pressure him to get out of the house more and interact with the world.
She was concerned because he spent hours on end holed up in his room playing violent video games like Call Of Duty.
A friend of Nancy said: 'He was like a ghost.'
It was revealed earlier this week that the mass murderer had not spoken to his father Peter for years - since he remarried in 2010.
Neighbours of Peter Lanza and second wife Shelley Cudiner told MailOnline that the pair packed up their car and left their affluent home in the Stamford suburb of Westover, Connecticut, shortly after being informed of Adam's involvement in the massacre on Friday afternoon.
In the wake of the devastation, Mr Lanza that he and his family are in disbelief at the atrocity his son committed at the Newtown elementary school.
'We too are asking why,' he said in a statement.
'Like so many of you, we are saddened, but struggling to make sense of what has transpired.
Nancy Lanza was divorced from Peter Lanza who lives in Stamford, Connecticut
'Our family is grieving along with all those who have been affected by this enormous tragedy.'
