BINGHAMTON, New York (CNN) -- Authorities defended the timeliness of police response to Friday's massacre at an upstate New York immigration services center as funerals were set to begin Sunday for two of the 13 slain. Jiverly Wong, 41, has been identified by police as the gunman in the Binghamton, New York, rampage. "No decisions by the police had any bearing on who died," Broome County District Attorney Jerry Mollen told reporters Sunday. The first officers arrived at the American Civic Association about three minutes after the first emergency calls were made Friday, according to a timeline by the Binghamton Police Department.
