NEWTOWN, CT. -- In grade school, he was fine.
In middle school, shy but friendly.
In high school, Adam Lanza become something of a loner. Withdrawn.
"He kind of disappeared," Tami Corsi said. "I was his friend.”
Lanza, 20, fatally shot his mother Nancy, 52, and drove to Sandy Hook Elementary School, shooting to death 20 six- and seven-year-old children as well as six faculty members Friday morning.
Multiple reports said Nancy, a divorced mother of two, had told a friend less than a week before the shooting rampage that she was very worried about Adam.
Nancy had said she was afraid of "losing her son," that his state of mind was "getting worse" and "she was having trouble reaching him."
Corsi, 17, a graduate of Sandy Hook Elementary School, said Lanza's slain mother used her own interest in guns to try to bring them closer together. She saw shooting guns as a positive -- perhaps a hobby for her son.
"Going to the range was a way of connecting," Corsi said.
Those close to Nancy said she owned firearms to protect her family. The guns used in the bloodbath were registered to her.
Corsi's mom, Victoria, said that in hindsight Nancy's method of trying to reach her son may seem strange, but there is nothing illegal about target shooting.
Who could have known he would eventually kill 27 people, including his mother, and take his own life?
Mark Tambascio, co-owner of the restaurant My Place and a close friend of the Lanza family, said Adam was a socially awkward man.
"It was hard to really engage in any real conversation. It was like his mind was going a million miles an hour," he told the Washington Post.
Transcripts show he was a bright student, completing high school in Grade 10 and taking college courses at 16.
Former high school classmates said Adam was a quiet, socially awkward teenager who carried a briefcase at school.
"He was invisible," said Dan Fisher, 18, who went to Newtown High School with Lanza. "You can barely remember him."
Mary Plavnicky recalled he was quiet and polite.
Others talked about his interest in the tech club and how he was afraid to look people in the eye.
But there was a time when he seemed just like a regular kid -- much like the ones he killed.
