An eyewitness saw the two men accused of murdering Michaela McAreavey emerge from her hotel room moments after he heard cries of anguish coming from inside, a court in Mauritius has heard.
Lawyer Mehdi Manrakhan, outlining the case for the prosecution, also told the jury in the island's Supreme Court about the nightmare moment her husband John discovered her lifeless body in room 1025 at the Legends Hotel.
The prosecutor said eyewitness Raj Theekoy was outside the room when he heard noises.
"He heard a female voice crying 'Agh, agh, agh' as if she was in pain," he said. He added that the witness then saw the two men accused of the crime leave the room.
Defendants Avinash Treebhoowoon and Sandip Moneea deny the charge of premeditated murder.
Mr Manrakhan said Michaela was the love of husband John's life and they had decided to spend a dream honeymoon in Mauritius after their wedding.
The prosecutor said Mr McAreavey had returned to their room after his wife, daughter of Tyrone Gaelic football boss Mickey Harte, failed to return from fetching biscuits to have with a cup of tea. He had to get a member of the hotel staff to open the door when no one answered.
"As soon as John entered room 1025 his worst nightmare began," said Mr Manrakhan. "In the bathroom John saw Michaela lying senseless in the bathtub."
Mr Manrakhan said medical examinations showed Mrs McAreavey died from asphyxiation due to compression of the neck. "Medical evidence is such that there can be no doubt that Michaela had been brutally killed," he said.
While the prosecutor told the court Treebhoowoon had confessed to police about his role in the murder - which he said was a robbery gone wrong - the jury later heard claims that he accused the police of beating the statement out of him. The prosecutor said Moneea emphatically denied involvement but the evidence would show he was a liar. The trial continues.
