Connecticut shooter would 'just shut down' in high school
Adam Lanza was prone to 'episodes' of withdrawal, even in the tech club he enjoyed, says a former advisor. He began taking college classes at 16.December 16, 2012|By Shashank Bengali, Molly Hennessy-Fiske and Kim Murphy, Los Angeles Times
"John Bergquist, who got to know Nancy Lanza at a neighborhood bar where both were regulars, described her as a New Hampshire farm girl turned sophisticate, a Red Sox fan with season tickets who traveled to ride hot air balloons, attend jazz concerts in New Orleans, and visit friends in London, New York and San Francisco, sometimes taking her older son Ryan along.
She drove a silver BMW. She also hunted with falcons.
Bergquist remembered going with Nancy Lanza to see another friend from the bar who was having trouble getting a turkey back into its coop. After watching the struggle, he said, Lanza who was elegantly dressed "lifted the gate, walked in, grabbed the turkey by the feet and said, 'This is how you do it.'"
Lanza had a soft side when it came to her younger son, he said.
"She always spoke very lovingly about him. She was devoted to him, catering to him and his limitations," he said. "He wasn't troubled or violent in any way he was a normal kid with a disability.
He had trouble being with people."
Nancy Lanza appeared to have made the decision to move so that Adam could attend college in another state. She started looking at schools in Washington state and North Carolina.
"She was willing to uproot her life," Bergquist said. "Nancy pretty much made it clear that she needed to be with him because he couldn't handle being on his own."
At Western Connecticut, Adam Lanza did not work toward any major or degree, said college official Paul Steinmetz, and
was still on the rolls at the time of the shooting, though not actively enrolled.
Few remember him."
