A retired NYPD officer grabbed a handgun and shot his two sons before turning the weapon on himself in his Long Island home late Sunday, authorities say.



Police say Irvin Noak, 61, got into an argument with family members during a party at his Bellport home around 11 p.m. His two sons, 22-year-old Aaron Noak and 30-year-old Irvin Noak III, intervened. Noak went and got a gun from his bedroom and shot them, police said. He then shot himself.

Both sons lived at the home and were taken to a hospital in critical condition. No one else was hurt.



Noak was pronounced dead at a hospital. He was an NYPD officer for more than 20 years, joining the force in 1989 and retiring in 2009.



The nature of the argument wasn't immediately clear.

Family friend Dequan Wilson who dropped off a tent for the party said when he last saw the family, everyone seemed happy. He added that he was shocked the party devolved into violence.

"Everything just seemed good yesterday. I talked to the dad, the dad was happy yesterday, everyone just seemed happy," he said.

Others in the neighborhood were surprised to hear gunfire.

"I'm still shaking from it," said Dilek Falco. "You know, my family lives here."
