"More recently, Alexis struck those who crossed his path as a man of sharp contrasts. He was learning the Thai language, visited Thailand for a month, was studying for an online degree in aeronautical engineering and seemed to enjoy conversing with diners, according to friends, customers and fellow worshipers. But some of them said he had an aggressive streak, one that caused them to keep their distance and avoid personal questions. "


Odd, though, given he was maybe a Buddhist to go postal like that. Buddhists are known for their patience and passivity...

Recently visiting Thailand...
