The family of murder suspect Fotis Dulos have been urged to come to the hospital to say their goodbyes as hopes faded today that he will ever wake up following his suicide attempt, DailyMail.com has learned.

Relatives are flying in from Greece and 'his affairs are being put in order', according to a source. In the slim chance that he pulls through, the father-of-five is likely to be severely brain-damaged and not in a position to stand trial.

'Doctors said brain damage is inevitable because of the amount of time he was unresponsive,' a source told DailyMail.com, who also said Dulos was legally dead at one point before being revived on Tuesday. 'He is completely reliant on life support,' the source added.

Dulos' lawyer, Norm Pattis, did not immediately respond to a request for comment on his client's condition but told a judge at Stamford Superior Court on Wednesday that his condition was 'dire'.

Rena Dulos, his sister who lives in their native Greece, is his closest living adult relative, and is traveling to New York with his niece Angelika after relatives got on the first flight available after being told Dulos had tried to kill himself by carbon monoxide poisoning on Tuesday.

Dulos was found in his home in Connecticut on Tuesday where he attempted suicide. He was awaiting trial for murdering his wife Jennifer. Prosecutors repeatedly asked for him to be denied bail as recently as last week, but the judge allowed him to remain on house arrest

Dulos, 52, was airlifted to Jacobi Medical Center in the Bronx to have treatment in a hyperbaric chamber.

Hyperbaric Oxygen therapy is used to raise the level of oxygen in a patient's blood and to reduce carbon dioxide levels as quickly as possible in cases of acute carbon monoxide poisoning.

Dulos is awaiting trial on murder charges for allegedly killing his wife Jennifer Farber Dulos, 50, in May last year in the middle of a two-year acrimonious divorce battle. He has denied having any role in her death.

Her body has not been found. Their five children, aged 8 to 13, are in the care of their maternal grandmother, Gloria Farber, in New York City.

Dulos faced the prospect of going to jail and having his $6 million bond revoked at an emergency court hearing on Tuesday over doubts over the equity of the real estate assets he put up as security.

Sources told DailyMail.com Dulos was 'losing his mind' at the prospect of having to go back into custody and that he tried to take his own life because of it.

Police officers performed a wellness check shortly before midday when Dulos did not turn up for his 12om court hearing.

The geo-location of his ankle bracelet showed that he was still at his home in Farmington, Connecticut.

Cops broke into the car to drag him out and perform CPR. Drone footage of the life-saving measures was captured by a news crew who had been at his Jefferson Crossing home on the intent of following Dulos to court for his hearing

He was then taken to UConn Health via ambulance before being airlifted to New York.

It is understood that he had been in the car for some time.

Dulos' new girlfriend, who has been intermittently staying with the real estate developer at his home, had left the home to go to the grocery store before he was discovered in the garage.

Dulos called Mark Motuzick of Capitol Bail Bonds in Hartford on Tuesday morning about taking over his bond. Motuzick had a conversation with Dulos around 10.30am when he called him back, and Motuzick that Dulos had sounded out of breath and 'loopy'.

Dulos had been on strict house arrest since last Thursday and could only leave his mansion to see a lawyer, a doctor or attend a religious service.

His bond hearing went ahead without him in Stamford, Connecticut on Wednesday.

Local police remained at his home to conduct an investigation but do not yet have a search warrant to enter.

After Dulos was discovered on Tuesday, there was confusion over his condition with his lawyer Norm Pattis initially saying that he was dead. He was later told that Dulos had a pulse.

At his bond hearing on Wednesday, the judge ruled that Dulos would not have to deal with issues over his bond unless he recovers.

If his bond had been revoked, it may have prevented family from visiting him in hospital.

Pattis told the court that guards are watching over Dulos at Jacobi Medical Center for his own protection.
