We're learning that Adam Lanza was interested in joining the military. He first made his interest known in 2009 when he was 17, around the same time he stopped taking classes at Western Connecticut State University, according to the Connecticut Post.
Connecticut Post's Marianne Gail Brown is the writer who broke the story.
Adam Lanza left few clues for investigators as to why he went on a shooting spree killing 27 people last Friday. A geneticist has now joined the investigation to help determine what role biology may have played.
Dr. Jim Fallon is a neuroscientist who studies the biological traits of psychopathic killers.
A relatively new science, he has analyzed the brains of more than 70 murderers to gain some insight into what factors contribute to the profile of a criminal - even tackling what Dr. Drew Pinsky said on the show last night that yes, people can be born to kill.
Three years ago, Dr. Fallon collected brain scans of seven family members, including his own, to asses their risk of developing Alzheimer's. After discovering that his father's ancestral line was connected to killers he decided to correlate his family's scans with those of the murderers he studies to find cues of aggression and violence.
Dr. Fallon found that certain areas of a killer's brain are often damaged. But three combined factors are what set off a murderer to commit the crime: violent genes, damage in some parts of the brain and exposure to traumatic experiences during childhood.

Vice President Joe Biden, the man leading the president's Gun Control Task Force, met with Administration officials and law enforcement officers from across this country Thursday to discuss possible proposals for reducing violence.
"We will act, and we will act in a way, that's designed, even if it's only designed to save one life, we have to take action," Biden said.
This meeting comes just as we're about to hear from the man everyone's been waiting for.
On Friday, the President of the National Rifle Association Wayne LaPierre will make his first public comments following the shooting.
This is a dramatic shift from the way the organization has reacted after previous mass shootings. In the past, the powerful lobbying group has kept radio silent after an attack.
