The LA Times reports:
On the outside, Nancy Lanza was the picture of contented motherhood: volunteering at her sons' school, gardening, keeping a picture-perfect home so well-ordered a neighbor described it as pristine.
Outside public view, say some who knew her, she had a struggle on her hands, and that was her son Adam: a brilliant but sometimes difficult boy.
Lanza battled with the school district over Adam and eventually quit her job, pulled him out of school and educated him at home, said her sister-in-law, Marsha Lanza.
"I know she had issues with the school. … In what capacity, I'm not 100% certain if it was behavior, if it was learning disabilities, I really don't know," Marsha Lanza told reporters. The investigation widened Saturday into the still-baffling shootings at Sandy Hook Elementary School in Newtown, Conn., with police releasing the identities of the 26 students and teachers they say Adam Lanza shot before turning the gun on himself.
His mother, police said, was shot at the family home before her son set out on his deadly rampage through the school.
"Adam, he was … definitely the challenge to the family in that house," Marsha Lanza said. "Every family has one. I have one. They have one. … But he was a very bright boy, he was smart."
