Not specifically a couple, but more than one person is being implied.
According to Paul Moyes OG made enquiries about a couple too;
"The second visit was about three months later and lasted more than an hour and that was to pursue a lead and to make sure we were convinced on our timeline.
"The lead was that a couple had climbed over the fence and the back garden wall and they asked if that was us. It wasn't."
The couple said they had no idea who the mystery couple were but the information was "a few times removed" and had been spoken about in restaurants in the area.

Paul and Susan Moyes were asleep when Madeleine vanished. Not quite the tabloid headline is it?
SnipPaul Moyes, 58, who is on holiday with his wife, Susan, said: "At 11.30pm there was a knock on the door. I went out in my dressing gown and there was a distressed gentleman there saying that a child had been abducted and could we help with the search. Everybody got involved."
The couple said the drama unfolded after what they described as "a fabulous day" in the Praia Da Luz resort.
It was as the couple were sleeping that three-year-old Madeleine was snatched from her parents' holiday
Mr Moyes said: "I felt quite shattered, to be quite frank. The people were themselves extremely sad and it was quite sad for everybody.
"We were quite emotionally shattered, seeing the family that distressed."
He said that among those who joined the search were many off-duty police in plain clothes who had been called in to help.
The couple said they remained on the search until 4am on Friday morning.
Mr Moyes described the resort as idyllic and safe. His wife added: "It is paradise."

SUSAN MOYES Sure. We went out for a meal about seven o’clock down in the town. We walked back about nine o’clock, round past, erm, the church, round past the supermarket, back to the apartment. Went out on the balcony about quarter past nine. Everywhere was peaceful, everywhere was lovely. We then went to bed.
We were woken up at half past eleven at night by one of the friends of the McCanns to say a little girl had been abducted. Those were the words she used. So we got dressed and joined in the search. We were out till about four in the morning with, oooh, about I dont know, thirty people, thirty other people maybe. The Mark Warner team were out with other guests at the Ocean Club.
