Elderly man suspected in Hamptons spa killing dies by self-inflicted gunshot

The man suspected of killing Sabina Rosas, a 33-year-old New York City artist, at an upscale spa in the Hamptons was discovered dead from an apparent self-inflicted gunshot wound, authorities announced Wednesday.

Thomas Gannon, 56, was found at his Honesdale, Pennsylvania, home, according to the Suffolk County Police Department. Police confirmed that Gannon and Rosas, an artist originally from Tajikistan, were involved in a “domestic” relationship, though no further details were provided.

A shocking scene at the Hamptons spa

Rosas’ body was discovered Monday by an employee at Shou Sugi Ban House, a luxury $1,000-per-night spa in Water Mill, Long Island. Authorities described the crime scene as particularly violent, with indications that Gannon was the last person seen leaving the spa without her on Monday morning. The incident has deeply unsettled the peaceful community of Water Mill.

Family and local impact

Rosas’ family remembered her as a “beloved daughter, sister, fiancée, and friend.” According to sources, she was reportedly engaged to a different man. Gannon, a father and business owner of Majestic Tile, Granite, and Flooring, resided in a three-bedroom home currently listed for sale in Honesdale.

As investigators continue looking into the circumstances of Rosas’ death, the tragedy has brought a grim atmosphere to the area, which is known for its serenity and high-end retreats.
