Nesconset teen fatally shoots ex-girlfriend, 18, then turns gun on himself, Suffolk police say

A Nesconset teen allegedly shot and killed his ex-girlfriend at his home Wednesday morning before turning the shotgun on himself, the Suffolk County Police Department said.

The victim, identified as Emily Finn, 18, of West Sayville, was pronounced dead at the scene, police said. The alleged shooter, who turns 18 on Thursday, was transported to Stony Brook University Hospital in critical but stable condition.

He allegedly used a legally owned shotgun and fired one shot at Finn before shooting himself in the face, said Suffolk police Det. Lt. Kevin Beyrer, commanding officer of the department's homicide bureau.

Beyrer said it was not immediately known who owned the firearm. The teen's name was withheld because of his age, the police said.

Finn had come home from college and gone to the boy's home on Shenandoah Boulevard in Nesconset to return his belongings after their relationship ended, Beyrer said.

"They had broken up and she wanted to speak to him face to face," Beyrer said on Wednesday afternoon at a news conference outside the home.

"They had broken up a couple weeks ago. From what we’re hearing," Beyrer added, "he took the breakup very hard."

The teenager faces a second-degree murder charge when he is arraigned at a later date, according to a police news release.

The boy's parents were at home at the time of the shooting, but working in the backyard. His father called 911 to report the shooting, Beyrer said.

There was "no domestic history" between the victim and the teen and no previous 911 calls regarding the young couple, Beyrer said.

On Wednesday afternoon, yellow police tape surrounded the two-story Nesconset home. Several police vehicles lined the street along with a mobile crime vehicle.

Neighbors, and teenagers who said they knew the boy, stood back and watched as detectives went in and out of the home.

Other family and friends also gathered at the scene, some crying as they spoke with police.

Neighbors said the family had lived in the home for several years, but they knew nothing about the shooting.

Bob Hennen, 77, who lives around the corner, said his grandchildren knew the teen and in the past had waited with the boy at the bus stop near his residence.

Hennen said he didn't hear gunshots, and he didn't hear sirens when police arrived at the home.

"It’s shocking," he said. "You don’t expect anything like this happening. This neighborhood is quiet."
