A catamaran captain was paddle-boarding along the St. Vincent shorewhen he came acrossaransacked yachtwith a broken, unrolled sail last month.
“It was not a very typical place to drop anchor,” Bernat Buj tells PEOPLE in an exclusive interview in the latest issue, on newsstands Friday. “And that caught my attention.”
Concerned, he boardedSimplicity, calling out three times in the hope of finding someone on board.
There was “a great mess throughout the ship, and I thought it was the scene of a robbery,” Buj says. “But when I entered a cabin and saw blood, I thoughtit could be something much worse.”

For more on the unfolding case of the missing American sailors in the Caribbean,subscribe now to PEOPLE, or pick up this week’s issue, on newsstands Friday.
After finding the couple’s abandoned yacht – 80 miles from their last reported mooring – in Wallilabou Bay, St. Vincent, the captain reported the “unoccupied sailing vessel” to the local Coast Guard Service Feb. 21.

Missing from the internal correspondence was the working theory between police forces in Grenada and St. Vincent that three Grenadian inmates who had escaped their holding cell the same day the couple went missing, had allegedly hijacked their yacht and thrown them overboard en route to St. Vincent.
The three fugitives – sailor Ron Mitchell, 30, Abita Stanislaus, 25, and Trevon Robertson, 19 – who had been arrested for a violent robbery in December, were re-apprehended on St. Vincent on Feb. 21.

An insider close to the investigation alleges to PEOPLE that at least two of the men have confessed to Ralph’s and Kathy’s murders.
The men, who were deported to Grenada on March 4, have not been officially charged in the case. Although the couple’s bodies have not been found, they are presumed dead.
Buj says he is still holding out hope. “I wish this story could have a happy ending,” he says.
