A New York couple has mysteriously vanished during a Caribbean vacation, with family members saying they've not heard from them in nearly two weeks. Orlando Moore and Portia Ravenelle set off on vacation to the Dominican Republic at the end of last month and were supposed to return home 11 days ago. Police say the couple checked out of their hotel in the town of Samana but haven't been seen since, and their car is still sitting in a parking lot at Newark airport. “He was supposed to return Wednesday morning, the 27th of March,” said Lashay Turner, Moore’s sister. “We haven’t seen him return so we started to call authorities.” The last picture of the couple posted to social media before they disappeared shows them riding horses. The families have reportedly been told they didn't make their flight home. There is also no sign of a car they rented on the Dominican Republic. “When these things happen, you always think of the worst, but we are hoping for the best,” said Edith Walters, Moore's grandmother.
