Taiwanese teen suspected of plotting US school attack ‘loved flame throwers and wanted to study criminology’
Sun An Tso, 18, had vowed to protect his classmates in the event of an attack, a friend said - but his collection of guns and ‘joke’ high school shooting threat scared police

People who know Sun An Tso, the 18-year-old Taiwanese exchange student charged in the US with threatening to shoot up his school, say he liked guns and flame throwers and had dreams of a police career.
Sun who has been jailed in the state of Pennsylvania, was “a child who really cares about things,” said Cheng Wei-ting, a tutor who home-schooled Sun in Taiwan’s main city, Taipei.
“He was an extremely simple and kind student, yet he would often have unusual ideas,” Cheng said.
Sun idealised the famed Taiwanese-American forensics scientist Lee Chang-yu and wanted eventually to study criminal psychology at an American university, his father’s friend Tuo Zong-kang told reporters on Thursday.
“He planned to study in the same fields as Lee, such as criminal psychology and forensics,” Tuo said.
