Binghamton, NY (WBNG Binghamton) 41 year old Jiverly Wong lived with his parents and sister in Johnson City.
About two weeks before he took the lives of 13 people and his own, he mailed a letter to a television station in Syracuse.
In it, Wong blamed police harrassment and a poor life for the action he would take at the ACA.
He included pictures of himself, sporting guns.
Wong was a gun enthusiast.
His sister had told media Wong was depressed about losing his job and was having trouble learning English.
Still, they were as shocked as any when he took a violent course of action.
His father, Henry Voong, spoke to the Syracuse Post Standard.
"My family and I are very upset regarding the tragedy involving my son and the victims and their families due to the shooting. We deeply regret what happened to this small Binghamton community," said Voong.
The family moved away not long after the shootings.
Jiverly Wong came to the US from Vietnam in 1990.
