“I could never have foreseen him doing that,” said John Powell, a former high school classmate.
Teixeira grew up in the suburbs of Providence, Rhode Island, according to public records and graduated from Dighton-Rehoboth High School in neighboring Massachusetts in 2020.
He toted around a “dictionary-sized” book on firearms and another about “tanks, planes and submarines,” former classmates told CNN.
“A lot of people were wary of him,” said Brooke Cleathero, a former classmate in both high school and middle school.
FBI agents interviewed at least one person who said a young man later identified as Teixeira began posting “what appeared to be classified information” on a server in December.
