From beyond the grave: An upstate New York TV station says it received a letter Friday from the man who was to massacre 13 people at an immigration assistance center later that day, before killing himself. “I am Jiverly Wong shooting the people,” opens the disturbing letter, which was dated two weeks before the shooting. Wong also mailed the station his driver’s license, gun permit, and photos of himself posing with his guns. He apologizes for his poor English and asks, “Of course you need to know why I shooting? Because undercover cop gave me a lot of ass during eighteen years.” Wong, 41, rants about the unnamed undercover policemen, who he says caused him to lose his job, ransacked his room, put him under 24-hour surveillance, and staged a car accident with him. The letter suggests Wong, a loner who was frustrated with his lack of English proficiency and had lost a factory job last November, was deranged and possibly suffered from schizophrenia.
