A forensic expert has told the Michaela McAreavey murder trial there was no DNA from the two men accused of murdering the Tyrone woman found on her body or at the crime scene.
Susan Woodroffe from Cellmark Forensic Services told the trial of the two hotel workers that their genetic material was not identified on a range of swabs taken from Mrs McAreavey or on samples recovered from the hotel room.
Ms Woodroffe was also asked to examine whether the DNA of defendants Avinash Treebhoowoon and Sandip Moneea and two other original suspects in the case - fellow Legends employees Raj Theekoy and Dassen Naraynen - was present on the samples.
While Ms Woodroffe found no matches from the four men on swabs taken from the victim's body, she did identify a potential match with Mr Naraynen on a key card for the room.
Mr Naraynen is facing a larceny charge in connection with the case in separate court proceedings.
But in relation to samples taken from Mrs McAreavey's neck, feet and fingernails, the forensic expert told the criminal court in Port Louis:
"There is no specific indication that any of Raj Theekoy, Sandip Moneea, Avinash Treebhoowoon or Dassen Naraynen have contributed to the results obtained."
Hotel workers Mr Treebhoowoon, 30, and Mr Moneea, 42, deny murdering the teacher, who was the daughter of Tyrone manager Mickey Harte.
Mrs McAreavey was found dead in her hotel room shortly after having lunch with her husband John while on honeymoon.
The prosecution claims she had returned to her room and caught the accused stealing in her room.
Earlier, Constable Seevathian of the Major Crime Investigation Team remained silent when asked what he did with one of the men accused of murdering Mrs McAreavey the morning after the crime.
One of the accused, Avinash Treebhoowoon has alleged that police beat a confession out of him in the wake of Mrs McAreavey's death in Mauritius last January.
Constable Seevathian was questioned by a defence solicitor about what he and his team did with his client in a two-and-a-half hour period between them arriving at the Legends Hotel and Mr Treebhoowoon making a statement in a local police station.
The court fell silent as the officer did not offer an answer.
After a few moments, Judge Mr Justice Prithviraj Fecknah intervened."Let the record show that the witness remains silent to this question," he said.
When further pressed, the officer told defence counsel Sanjeev Teeluckdharry that he was questioning the accused about his movements.
But he repeatedly answered "I can't remember" to a series of other questions posed by the lawyer about his involvement with the accused in the days after the murder.
