This stunning grand mansion, nestled in two acres of lush gardens in the Hamptons, hides a dark secret.

The six-bedroom home was once location of the infamous 2001 murder of Wall Street financier Ted Ammon, who was bludgeoned to death in his bedroom by his wife's handyman lover Daniel Pelosi.

The English Manor style home, on Middle Lane, boasts six bedrooms, six-and-a-half baths, as well as a gourmet kitchen, solarium, and library.

The mansion comes also features an exercise room and heated pool, with accompanying pool house, all nestled within 2.2 acres of land with its own pond, in East Hampton Village.

The Ammon twins have not lived in the home since their father's horrific murder, but have rented out the property to several families over the past 16 years.

'Alexa and I are now ready to sell our childhood home as we are both moving forward with exciting new ventures,' said Greg Ammon.

'We truly hope our family home finds the right buyer who can enjoy the many happy memories we had here and appreciate the true beauty that it has to offer.'

The brother and sister were adopted as toddlers from a Ukrainian orphanage by Ted and his wife Generosa Ammon and for a while, they had the picture perfect family.

But after 17 years of marriage, the relationship began to crumble. Following their separation, as Generosa fought for half of his $80 million fortune, things turned ugly.

They were just days from finalizing their divorce when, on October 22, 2001, he was found bludgeoned to death in the bedroom of his weekend Hampton's home. As they were still technically married, Generosa inherited 50 per cent of his estate, while the other 50 per cent went to Ammon's foundation - as stipulated in his will.

Greg founded Big Flower, a Hamptons lifestyle brand with a flagship in East Hampton and expansion plans in the fall. Alexa recently graduated from USC School of Cinematic Arts and is currently pursuing a career in film and photography.

Generosa's boyfriend Pelosi, a married electrician from Long Island, was convicted of the murder in 2004 and is imprisoned at Attica Correctional Facility in upstate New York. He's eligible for parole in 2031.

The twins, who were at their father's house in Manhattan when their 52-year-old was bludgeoned to death, was initially told by their mother that he had killed himself, before they learned the truth.

The children were left without parents for a second time when Generosa was diagnosed with breast cancer and died in August 2003. The children went to live with their aunt in Alabama.

Pelosi, who had been battling for a part of the fortune left by his late wife, always maintained that Generosa hired a hit man to kill her husband. But the twins admit they were not convinced he was a killer until he was convicted.

'I still had doubts up until that point,' Alexa told Katie Couric in 2012. 'I was so convinced he was innocent. I don't know what he did to my mind. He's a psychopath .

Both Alexa and Greg are now certain he was to blame, and say they choose to believe their mother was not a part of their father's death.

Despite enduring such tragedy before they were teenagers, the twins pulled through.

'We had each other so that was one thing,' Greg said. 'It was not easy .'
