The gunman who ran amok in Binghamton, N.Y., killing 13 people at an immigration center, apparently worked for Inglewood sushi caterer for about seven years until he disappeared in 2007, the Los Angeles Times reported.
Linh Voong, 42, also known as Jiverly Wong, worked at Kikka Sushi as a delivery man for seven years, Paulus Lukas of the company told the Los Angeles Times.
Wong apparently immigrated to the United States from Vietnam with his family when he was a boy.
Lukas said the man he knew as Wong was a conscientious, good worker.
"He was really good at doing his job," he said.
Lukas said Wong simply failed to show up for work one day. In early 2008, Wong called Lukas to ask him to send his W-2 to an address in New York, The Times reported.
Wong, who killed himself at the end of the rampage, was living in nearby Johnson City, N.Y. He had worked at a Shop Vac assembly plant until it closed in November.
People who knew Wong on the east coast described him to the New York Daily News an an angry loner, who loved guns, hated America and talked about assassinating the president.
Witnesses said he walked into the immigration services center, locked the exits and opened fire with two semiautomatic pistols, both of which were apparently registered.
