A Nesconset teenager has been indicted on a second-degree murder charge for what prosecutors describe as the execution-style killing of his ex-girlfriend during Thanksgiving break.
Suffolk County District Attorney Raymond A. Tierney announced that Austin Lynch, 18, was formally charged after allegedly shooting Emily Finn, 18, in the back of the head with a family shotgun on November 26, 2025.
“This is a tragic case,” District Attorney Tierney said in a statement. “Emily Finn should still be alive and back at college. Instead, the defendant allegedly robbed her of that experience and her future.”
According to investigators, Finn-home from her freshman year at SUNY Oneonta-went to Lynch’s home on Shenandoah Boulevard North in Nesconset that morning to speak in person about the end of their three-and-a-half-year relationship. Finn had ended the relationship two weeks earlier. Prosecutors say Lynch became obsessive afterward, repeatedly calling and messaging her, even after she blocked his number.
When Finn attempted to leave the home, Lynch allegedly shot her at point-blank range from behind. He then reportedly turned the gun on himself, causing severe facial injuries.
Lynch’s parents, who were in the backyard at the time, rushed inside after hearing the gunfire. Lynch’s father called 911, telling dispatchers that his son had shot Finn and himself. Responders found Finn deceased, still holding her car keys, with her purse and coat beside her.
Lynch was transported to Stony Brook University Hospital, where he was treated for extensive facial trauma, including fractures and a cranial leak.
On December 4, Lynch was arraigned before Judge Philip Goglas, who ordered him remanded without bail. If convicted, he faces 25 years to life in prison. He is represented by attorney William Wexler.
The case is being prosecuted by Dena Rizopoulos of the Homicide Bureau with Keri Wasson of the Major Crime Bureau. Detective Adam Quinones of the Suffolk County Police Homicide Squad led the investigation.
Criminal complaints and indictments are merely accusatory instruments. Defendants are presumed innocent until proven guilty. No one is above the law.
