Man Admits To Fatally Shooting Woman In Her Long Island Home On New Year's Eve: SCDA

SUFFOLK COUNTY, NY — Detrich Emanuel, 31, admitted to fatally shooting Kristine Costantino, 40, of Middle Island, in her home on New Year's Eve in 2023, Suffolk County District Attorney Raymond Tierney announced Tuesday.

Emanuel, who is homeless, pleaded guilty to first-degree manslaughter, the DA said. He is expected to be sentenced to 20 years in prison followed by five years of post-release supervision.

"After a minor verbal argument, this defendant shot Kristine Costantino, killing her in her own home," Tierney said in a news release. "While this plea cannot undo the immense pain caused to the victim’s family and loved ones, we hope it spares them from the additional trauma of a trial and keeps this defendant from hurting anyone else in the community."

At 11:24 a.m. Dec. 31, five people, including Emanuel and Costantino, were at Costantino's apartment when the two of them began a "tense verbal exchange" with each other prosecutors said. Emanuel then pulled out a firearm, pointed it at Costantino's chest, and shot her, authorities said.

Emanuel called 911 to report the shooting but fled the apartment before law enforcement arrived, officials said.

When police arrived to render aid, Costantino repeatedly said Emanuel’s name, investigators said. Costantino was later pronounced dead at Stony Brook University Hospital, the DA said.

Emanuel was arrested in the Bronx on Jan. 14, Tierney said.

In July 2018, prior to his arrest in the shooting of Costantino, Emanuel was convicted in Queens County of second-degree attempted burglary, the DA said.

He is due back in court on Oct. 10. He is being represented by Matt Tuohy. Tuohy did not immediately respond to Patch's request for comment.
