(New York Post) Crazed kid-killer Adam Lanza was a troubled “genius” who was painfully awkward and shy.

“I know he had issues,” said Beth Israel, whose daughter, Alex, went to school with Lanza. “He was a really troubled kid. I think he had learning disabilities.”

Adam’s brother told investigators that the gunman was autistic, sources said. Israel described him to The Post as a sort of autistic savant, saying he was “very smart, but he had issues. He was a real genius.

“He was just a weird kid. He was a very quiet kid, a shy kid, maybe socially awkward,” Israel added.
