The brief, enigmatic life of mass-murderer Adam Lanza

A Connecticut official said the mother of the gunman in the Connecticut massacre was shot four times in the head before her son went to the elementary school where he gunned down 26 people.

Adam Lanza then killed himself with a single bullet to the head from a 10 mm gun, and the bullet was recovered in a classroom wall.

...
CBS News' Pat Milton reports source briefed on the investigation said Nancy Lanza was demanding of her children. Even though Adam was highly intelligent, she pressed him to high standards and even pressed her sons to measure up at the shooting range where she taught them to shoot, the source said.

...

As CBS News' Miller notes, there's been very little paper trail for the 20-year-old Lanza. "It's been a mystery. ... He got his GED a few years ago ... but there's no picture of him holding a job or getting higher education."
