A search has intensified for an American couple who mysteriously disappeared on Monday after going jet skiing while vacationing in Barbados.

Oscar Suarez, 32, and Magdalena Devil, 25, arrived on Saturday and were vacationing on the Caribbean island, taking part in activities while staying at the Discovery Bay Hotel.

On a sunny Saturday, they rented the watercraft vehicle and sped off into the sunset wearing like jackets for safety. But the local operator where they rented the vehicles grew weary when the couple never returned after 30 minutes, according to the Royal Barbados Police, NBCNews reports.

Police received word on Monday that the Montclair, N.J., couple were missing and their watercraft was never returned. A search ensued but Suarez and Devil have yet to be found, authorities said. They reportedly rented a jet ski from an operator at Holetown Beach, on Barbados’ west coast.

“We pray to arrive there to some good news about Oscar and Maggie,” Cruz wrote on social media as she thanks people for their prayers.

Suarez’s cousin, David Monzon told The New York Post, “We are devastated. You hear stories like this, but it never really hits you until it’s your family. We just want answers.”

According to local station News 12 New Jersey the couple’s family members were en route to the island on Wednesday.
