DNA linked to a man accused of possessing heroin was found on two capsules containing the drug discovered in a hotel safe, the Supreme Court heard.

Valerie Blackmore, a forensic biologist, told the court that of 12 samples sent to her for testing, she was able to identify two genetic profiles, which she referred to as Male A and Male B.

While Marc Daniels, counsel for David Osadebay, conceded that his client was Male A identified in DNA testing, he questioned Ms Blackmore about how the DNA could have come to be on the capsules.

She said that direct transfer — the individual having physical contact with the object — was more likely to cause DNA to be left than secondary transfer through an “intermediary” such as a hotel duvet or personal items.

However, Ms Blackmore added she could not say for sure how or when DNA came to be on the capsule.

“What it does not do is say what happened in this particular situation,” she told the court.

Ms Blackmore also confirmed that she had not been sent any samples taken from a hotel duvet to be tested.

Mr Osadebay, 38, has denied a charge that he possessed diamorphine, commonly called heroin, with intent to supply on August 4, 2023.

The court previously heard that Mr Osadebay, a British national, travelled to the island on July 31 and was arrested on August 4, the Friday of that year’s Cup Match.

A search of his hotel room revealed pellets of heroin hidden in the room’s safe.

As the trial continued yesterday, Detective Constable Assad Ackle told the court that on the afternoon of August 4, 2023, he received information that an individual by the name of Joshua Webb was suspected of entering the island using fraudulent documents.

At about 6.30pm, he and other officers were sent to the Royal Palms hotel to search the room where the person of interest was believed to have been staying.

During the search of the room, hotel staff opened the room’s guest safe.

“Inside the safe was a sanitary bag,” he said. “Contained in the bag were 11 oval-shaped pellets wrapped in plastic wrap.”

Mr Ackle said that in addition to the bag, he noticed a UK passport with the name Joshua Webb, as well as a British Airways boarding card and bank cards carrying the same name.

“I think everything in the safe was with the name Joshua Webb,” he said.

He also noticed another oval-shaped pellet on the bottom of the safe.

Under cross-examination by Mr Daniels, Mr Ackle said that the defendant gave his name as David Osadebay during an interview on August 7.

He accepted that after learning the defendant’s name, he sought information online and found that Mr Osadebay performed music under the stage name “C Biz”.

The court also heard from Detective Sergeant Seymour Foote, who supervised the search of the hotel room and took photographs of the items seized.

Mr Foote told the court he understood that lab reports confirmed that the pellets found in the sanitary bag contained 9 per cent diamorphine, while the pellet on the floor of the safe held 11 per cent diamorphine.

Questioned about the photographs he had taken, he accepted that the seized items had been photographed on the hotel room’s bed, along with items of clothing found in the room.

However, he said he did not place them there himself.

The trial continues.
