Missing airman Corrie McKeague’s mother has accused his father of trying to close down the investigation.
Nicola Urquhart said his recent claims had led to her son Darroch reading RIP messages and facing accusations he had given up on his brother while on his honeymoon.
Martin McKeague, of Cupar, said he believes his son is somewhere in the Suffolk waste system and that an interim death certificate was being sought.
Nicola, of Dunfermline, has insisted that a coroner refused to issue a death certificate.
She said: “We feel that it is Martin’s intention, he wants to close this investigation down.
“He is trying to prevent us from getting our answers and [to] make people just move on.”
RAF gunner Corrie was 23 when he went missing after a night out in Bury St Edmonds on September 24, 2016.
It is believed he may have fallen asleep in a bin picked up by a refuse lorry, but no trace of him was found during extensive searches of a nearby landfill site.
In an emotional video posted to the Find Corrie Facebook page, Nicola said: “We are still looking for Corrie, Corrie is missing.”
The family have recently celebrated Darroch’s marriage and the engagement of Corrie’s other brother Makeyan.
Accusing Martin of attacking her and her sons, Nicola said: “It’s causing them distress and absolute heartache in their search for their brother and nobody has the right to stop them or me from doing what we feel we need to do to be able to get answers for Corrie.”
She said Darroch and bride Leah should be enjoying their honeymoon.
“Instead,” she said, “they have had the press and people messaging them with condolences.
“Darroch has had people asking him why he has given up on his brother. How can he just leave him in a landfill?
“Darroch, Makeyan and I, our family, are not there, we are not ready to start mourning [Corrie] yet and we should not be getting forced into that and Martin is trying to do that.”
Nicola insisted the police remained unable to categorically state where Corrie is and that the family would continue to work with Suffolk Constabulary.
She added: “There are other possibilities, not probable, but there are other possibilities.”
Since his statement on his Facebook page last week, Martin McKeague appears to have altered his privacy settings.
Police said in March that the investigation was being handed over to a cold case team as there were no realistic lines of inquiry left to pursue.
