Carlow woman Martha Nolan-O'Slattara was found dead on a yacht in Montauk, New York on Tuesday, August 5.

Martha Nolan-O’Slatarra, the Carlow woman who was found dead on a yacht in Montauk, New York, on Tuesday, August 5, was due to visit Ireland this week, her grieving mother has revealed.

Nolan-O’Slatarra, 33, was found dead on a boat docked in Montauk on Tuesday, prompting an investigation by Suffolk County Police Homicide Squad detectives.

East Hampton Town Police responded to a 911 call from a man reporting a woman unconscious on a boat docked at the Montauk Yacht Club, on Star Island Road, at approximately 12 am.

Good Samaritans attempted to perform CPR, but the Manhattan-based Irish woman was pronounced dead on the boat by First Responders.

Police later said that an autopsy conducted on Nolan-O’Slatarra "did not show evidence of violence and her final cause of death is pending further examination."

Anyone with information on this incident is asked to contact Suffolk County Police Homicide Squad detectives at 631-852-6392.

A spokesperson for the Montauk Yacht Club said: “We are saddened to learn of the tragic incident that took place.

"Our team is cooperating with law enforcement in their ongoing investigation and remains committed to the safety and well-being of our guests and staff. 

“We have no further comment at this time.”

Originally from the Monacurra area of Carlow town, Nolan-O'Slattara was a graduate of University College Dublin and emigrated to New York City in 2015.

The successful businesswoman founded the fashion and accessories brand Duper as well as the swimwear and eyewear brand East x East.

She also launched the marketing agency Brand Growth Consultants and was the Director of Operations at K4 Capital Management.

Martha Nolan-O'Slattar emigrated from Ireland to the US in 2015.

Last night, Martha's mother Elma Nolan told the Irish Independent that she is "numb and in shock" following her daughter's death. 

“My younger daughter, Jacqui, arrived in on Tuesday night and she was crying and shaking," Elma said.

"She said, ‘I have terrible news, Martha’s dead.'"

Elma told the Irish Independent that during a phone conversation with a homicide detective in Montauk, she was directed to the medical examiner’s office for more information.

“The detective said Martha was dead, that he was sorry,” she said. “I asked him where she was, and he said she was on a boat.

“I asked him who she was with. He said he couldn’t release information because it was too early on in the investigation. He instructed me to phone the medical examiner’s office.”

She continued: “I don’t know what happened. We weren’t told anything about the circumstances.”

The grieving mother said she last spoke with her daughter on July 29 about plans Martha had to visit home in Ireland this week.

“She wanted to know if I would be around to pick her up,” Elma recalled.

“It was a very quick call because she is so busy, but that’s the last time we spoke.”

It is expected that Martha's body will be released to her family on Saturday.
