‘She has no more power over me or anyone else’. 

Thomas Gannon sent those chilling words to his ex-wife in the final text message he would ever send.

Less than 24 hours earlier, he bludgeoned an aspiring young artist to death with a hammer in a luxury Hamptons resort.

The 56-year-old man took his own life after escaping from Unit 12 at the $1,500-a-night Shou Sugi Ban House, where the lifeless body of 33-year-old Sabina Rosas, also known as Sabina Khorramdel, was discovered.

Gannon exited the hotel located in the town of Southampton and ordered an Uber, which drove him 220 miles to his cabin in Berlin Township, Pennsylvania.

There, he fatally shot himself after confessing to the mother of his two children why he had committed the unspeakable crime.

‘She was the real devil,’ Gannon wrote. ‘I was running out of money, she wouldn’t stop taking it.

‘I had no way to stop her, she was going to kill me. I stopped her yesterday, the only way was to kill her’.

His confession is part of new police files that the Daily Mail has obtained exclusively, providing insights into the murder that shocked the Hamptons community.

The document uncovers Sabina’s last moments and introduces shocking details of the crime carried out in the hotel, which has hosted celebrities like Kate Hudson and Gwyneth Paltrow.

Police also included a detailed timeline and witness statements that paint a truly horrifying picture of what really happened in Unit 12.

Gannon had checked into the wellness retreat with Sabina on Saturday, October 26, 2024, at 8.51 pm. 

The following day, video surveillance captured the couple leaving the hotel dining room and walking towards Unit 12 at 9 pm.

Detectives confirmed that would be the last time the victim would be seen. 

At 8am on Monday, October 28, 2024, the hotel host supervisor sent Gannon a text about check-out. She said he had requested a late check-out. 

Ten minutes later, the supervisor watched Gannon walk past the front desk towards the front of the hotel.

Roughly four hours later, at 12:25 pm, a housekeeper knocked on the door to clean the room. Receiving no response, she entered and found the horrific scene: Sabina’s naked, bruised, and bloody body lying on the bed.

The curtains were drawn, and bloodstains marked the sheets and floor. She told the police she was so shaken by the sight that she closed the door and informed two co-workers.

Through the sliding glass door, they saw Sabina lying motionless on the bed, covered in blood. The horrified employees then called 911. 

The death report indicated that Sabina had been beaten about her head numerous times with a blunt force object, causing her death. The head injuries she sustained were consistent with a hammer.

Sabina had multiple defensive injuries, fingernail gouges on her arm, extensive cranial fractures, aspiration of blood in lungs, air embolism in the heart, and blunt force trauma to the head, as per the autopsy report.

One of the hotel staff remembered Gannon as a returning guest since 2019

Gannon and Sabina checked into the hotel on Saturday, October 26 close to 9 pm

One of the hotel employees remembered that Gannon had been a returning guest at the resort since 2019. She also told police that she remembered hosting the couple in May 2022. 

Sabina had an ex-husband, a husband – who was listed as one of the people who identified her body – and a close friend, Ryder Iwata, who referred to himself as Sabina’s fiancé. 

Iwata said he had been in a relationship with Sabina since they met as students at Purchase College in New York in 2016, and said they planned to get married as he described her as ‘my person.’

The exact nature of Sabina’s relationship with Gannon is unclear. Iwata said Gannon helped support her art career and even paid for an apartment in her native Tajikistan, but said Gannon would use this to ‘control’ her.

‘(Gannon’s) money suddenly became the control he would use to stay in her world and her orbit,’ he told DailyMail.com.

He added that he knew Sabina was in other relationships but they did not discuss it, and although he knew of Gannon’s existence he did not think Gannon knew she was engaged.

Sabina’s former mentor and professor at Purchase College, Liz Phillips, told DailyMail.com that she understood Gannon ‘supplied her with money’ and ‘seemed to worship her imagination and various quests’, and described their relationship as ‘romantic.’

Ryder Iwata, a fashion designer and Sabina, a multimedia artist, met at SUNY Purchase in 2016  and shared a special relationship. Iwata said Gannon was ‘head over heels’ for her 

Iwata described Gannon as ‘very odd’ and ‘socially inept’, and said Sabina’s entire demeanor would change around him.

He said Gannon would fund Sabina’s artistic efforts as a ‘muse’ of sorts, and said Gannon was ‘head over heels’ for her but was often ‘very possessive.’

Iwata said that he knew Gannon as an art benefactor to Sabina, and although they only met once he was left with a strange vibe from the alleged killer.

He said Gannon helped move a piece of furniture into Iwata’s Brooklyn apartment last year, and found his behavior to be ‘weird.’

‘Sabina didn’t want me talking to him,’ he continued. ‘She wasn’t acting like herself. She apologized for the weirdness and went back into the car… It felt bizarre to me.’

Sabina’s heartbroken family said in a statement upon hearing news of Gannon’s death that they their family has been left ‘with a mix of sorrow and frustration.’

‘While we are deeply saddened by the tragic loss of life, we also feel a profound sense of injustice,’ the family said.

‘Sabina deserves justice, and we were seeking accountability for her death. The loss of the suspect means we will never hear the truth about what happened to her. This outcome has robbed us of the opportunity to find closure through the legal process.

‘As we navigate this painful moment, we urge the world to remember Sabina for who she was as a person, her spirit, the important work she did and the art that she created and brought life for us.

‘The fight for truth and justice continues in our hearts, and we will honor Sabina’s memory as we seek to ensure that her story is never forgotten.

‘Thank you for respecting our family’s privacy as we cope with this profound loss.’

Thomas Gannon’s home in Honesdale, Pennsylvania where he shot himself October 29, 2024

Gannon fled in an Uber driven by Ozan Musullo to his home 212-miles away in Honesdale, Pennsylvania.

He recalled that Gannon was standing on the sidewalk outside the private gated resort and remembered he had been dressed in a dark long jacket and had fair skin and light eyes.

He said he seemed ‘miserable,’ and recalled that after he settled in the back of the passenger seat, he stared out the window for a while before falling asleep over the course of the 3.5-hour drive.

When Musullo got closer to the destination, Gannon helped him navigate. When he left his car, he remembered he had not given him a tip. 

Gannon’s ex-wife contacted police to conduct a welfare check after she received a troubling text. The message sent on October 29, 2024 at approximately 8.09 pm was Gannon’s confession 

In the note, he detailed his motivations alleging manipulation and financial ruin caused by the victim, as per the police report.

‘She took everything from me. You and the kids, my family, my friends, two million dollars in forced trips, jewelry and the most expensive clothings, shoes, and bags money could buy, including 500K in cash.’

‘She took our multi-million dollar businesses from us, she took our kids future from us. She took my life. 

‘I’m sorry there was nothing I could to stop her. She has an evil power that was not stoppable.’

‘She took control of my mind and everything about me, I cannot live with all for this now.’

After he apologized to his ex-wife and children and told them he loved them he killed himself with a .380 semi-automatic handgun.
