A man from Monroe, New York, who was vacationing in Turks and Caicos late last month is missing after leaving his rental home on June 25.

Brian Tarrence, 51, was last observed leaving his condo around 3:30 a.m. at the Paradise Inn in Grace Bay, Providenciales, Turks and Caicos, as detailed in a missing persons flyer from the Royal Turks and Caicos Islands Police Force.

“Everything appeared to be going normally for the couple, and then he unexpectedly walked out of his condo, which is situated in a very secure area in the middle of Grace Bay Road,” Carl DeFazio, the Tarrence family’s private investigator, informed Fox News Digital on Tuesday. “We have video footage of him walking into town before he vanished without a trace, and there has been no communication from him since.”

Tarrence, who recently relocated from Monroe to Manhattan, traveled to Turks and Caicos with his wife of one year on June 22, with plans to return on June 29.

The PI added that he is “very proud of the response from the local businesses and people on vacation” who have been offering their assistance after he posted Tarrance’s missing persons flyer “everywhere in Turks and Caicos.”

He added that he has no reason to suspect any kind of criminality in Tarrence’s disappearance at this point, but anything is possible with so few answers six days after he vanished.

DeFazio said that in missing persons cases like this one, he typically tries to establish a behavior pattern, trying to hone in on activities the missing person likes and does not like to do. He also tries to determine how familiar the missing person is with the area he or she vanished from and what he or she frequented in that area.

Then, he canvases the area where the person disappeared and tries to track down phone and smartwatch records to track the person’s last known movements.

Turks and Caicos police are asking anyone with information about Tarrence’s disappearance to contact 911 or Crime Stoppers at 1-800-8477.
