Boyfriend Suspected of Killing Artist at Luxury Hamptons Spa Is Found Dead in Another State

A day after police found the body of Sabina Rosas at a luxury spa in Long Island, authorities located the body of her boyfriend, who police suspect killed Rosas before taking his own life. 

On Tuesday evening, investigators found the body of Thomas Gannon, 56, the man suspected of killing Rosas, in his home in Honesdale, Pa., the Suffolk County Police Department confirmed to PEOPLE. 

Thomas was Rosas’ boyfriend, ABC 7 reported, citing unnamed sources. 

Rosas, 33, was found dead by a staff member at a Water Mill, N.Y., resort on Monday, Oct. 28, the Suffolk County Police Department previously said in a statement obtained by PEOPLE.

Police responded to the Shou Sugi Ban House in the afternoon and found Rosas’ body with signs suggesting she had been a “victim of violence,” authorities said in the statement. 

Rosas was a native of Tajikistan, per local weekly outlet The East Hampton Star.

She also went by the last name Khorramdel, CBS News, NBC New York and The East Hampton Star reported.

A Central Asia-focused arts magazine Ruyo Journal, which was co-founded by Rosas, announced her death on Wednesday in an Instagram post.

“Driven by her incredible energy and vision, Sabina moved walls so that gardens could flourish, inviting everyone seeking light. She shared everything she had and supported all of us,” read a part of the statement. 

“A beautiful soul and a gifted artist, she left an impactful legacy in the arts of Central Asia,” the statement continued. 

In a statement, her family identified her as  “Sabina Khorramdel” and mourned the loss of their “beloved daughter, sister, fiancee and friend,” per NBC New York.

Her mentor at the State University of New York-Purchase said she was “an extraordinarily creative and capable artist/painter.” CBS News reported.

Shou Sugi Ban House is a destination spa in the Hamptons, according to a Vogue spa guide.

The upscale spa earned a Goop review praising its “three acres of lush Hamptons woodland.”

Shou Sugi Ban House did not respond to PEOPLE’s request for comments.
