The search for a young couple missing at sea after they went overboard from a cruise ship in the Pacific was called off Friday.
Paul Rossington, 30 and Kristen Schroder, 27, were reported missing on Thursday morning when the Carnival Spirit docked in Sydney, Australia, after a 10-day cruise.
Surveillance cameras showed they had gone over the side on Wednesday evening.
Detective Superintendent Mark Hutchings, of New South Wales Police, told the APTN news service that he had studied the video footage.
"It was at night time so you can't really tell whether it was a male or female that went over first, they went over around the same time," he added. "But again, without further investigating everything else that may have gone one, it was a bit hard to speculate exactly about what occurred just from that (footage)."
However police are still investigating whether they jumped or if there had been some kind of accident.
Search-and-rescue planes and boats had been scouring an area covering about 500 square nautical miles off Australia's eastern coastline.
“We’ve called off the search now … and it won’t resume,” a New South Wales Police spokesman said.
However, he added: “It will resume if we get any confirmed sightings … concrete evidence that, yes, they are out there and they need rescue.”
He said officers would try to determine the circumstances of their disappearance.
“They will obviously thoroughly investigate this, what’s behind it, what happened,” the spokesman said.
The Australian Broadcasting Corporation said Rossington and Schroder were from the small New South Wales town of Barraba.
Resident Paula McIvor told the broadcaster that the "community is very, very saddened.”
"We're a very tight-knit little community here. We all know each other and we're very shocked by the news,” he added. "We feel for all the relatives and family of these people."
Another local resident, John Bishton, told the station that Rossington, a paramedic, was well-liked. "He's a consummate professional," he said.
