Peter A. Kaisen, a 76-year-old veteran from Islip, N.Y., committed suicide in the parking lot of the Northport (N.Y.) Veterans Affairs Medical Center Aug. 20. The New York Times reported that sources within the facility had said that frustration with his waits for treatment might have led Kaisen to shoot himself. A VA staffer at the facility’s emergency room may had turned the man away earlier that day, according to the report. A VA spokesman later said that there was no report that Kaisen had presented himself to the emergency room, however.
