Armed with two handguns, the killer entered the centre in the town of Binghamton 150 miles north of New York city at about 10.30 am local time and opened fire the moment he stepped through the doors.
The gunman then quickly moved into a classroom where students were preparing for exams in US citizenship and sprayed the room with bullets, killing all of his other victims, according to Joseph Zikuski, the Binghamton police chief.
Officials were unable to pinpoint a motive for the killings, but local news reports revealed that Voong had recently been laid off from his job with IBM.
So, an immigrant gets laid off and wreaks his revenge by killing a bunch of newer immigrants. What a fucking nutter.
