An American tourist has disappeared during a trip with his wife.

Brian Tarrence, 51, has not been seen since he unexpectedly left his Airbnb in Turks and Caicos on June 25.

The couple arrived at this popular tourist destination on June 22, planning to depart a week later, according to a report by Fox News.

Tarrence had his cellphone and wallet when he left the accommodation at around 3:30am local time, according to private investigator Carl DeFazio.

DeFazio explained that Tarrence and his wife had been enjoying their vacation before he vanished.

Tarrence had been on a boat trip with his wife – just hours before he vanished. 

“That evening, his wife went to bed, and when she woke up, he was gone,” DeFazio said.

Cops have since released images of Tarrence leaving the Airbnb on foot.

DeFazio was left bewildered when watching the video of Tarrence leaving the Airbnb.

“That’s a little bizarre in itself,” he told the outlet News12.

“He’s in the middle of town. His wife was sleeping.”

He was last seen in the Grace Bay area of Turks and Caicos.
