STATEN ISLAND, N.Y. -- An NYPD officer pronounced dead Tuesday morning from an apparent self-inflicted gunshot wound was identified by neighbors and sources on scene as 31-year-old Yong Yun.

Assigned to the 120th Precinct, Yun and his partner were named "Cop of the Month" in 2014 by the Staten Island Chamber of Commerce.

Yun had a gunshot wound to the neck when police responded to his residence on Dorval Avenue, according to an NYPD spokeswoman.

Police have yet to confirm his identity.

Neighbors said he lived at the house with his parents and other family members.

They said the family has been there for more than 10 years.

Earlier this month, Yun and his partner were praised in a Tweet from the 120th Precinct for getting a gun off the street.

"He loved being a cop," former neighbor Richie Manzi told the Advance.

Neighbors said Yun's father owned a fish store in Rossville and they would see the mother and father arrive home around the same time each evening.

"Every night the mom and dad would wave hello," Manzi said.

A handwritten sign on the door Tuesday at Han's Fish on Rossville Avenue read "we have trouble (at) home, about 2-3 days."

A few other people who appeared to be family also frequented the house, they said, including a man who appeared to be around the same age as Yun who stopped by the crime scene briefly Tuesday. He declined to comment.

"(Yun) always used to ask how I was feeling, if I ever needed anything" Manzi said. "He always asked about my daughter."

A neighbor across the street said Yun was extremely polite, to the extent of asking if he could park his car in front of the man's house during road work.

The incident remains under investigation, pending, in part, an autopsy report from the Medical Examiner's office.
