A female visitor, whom Graham Dwyer described as his girlfriend, broke off all contact with the murderer in 2020, we can reveal.
Sligo community worker Charmaine Davidson, who Dwyer had listed on a prison visitor log as his "girlfriend", stopped visiting the depraved killer in mid-2020, we have learned - and never had any video calls with him during the pandemic.
The visits and calls ceased despite Ms Davidson previously keeping in regular contact with Dwyer for over four years.

Sources say Ms Davidson, who denied to this outlet that she was Dwyer’s girlfriend in April of that year, appears to have cut off all contact with the infamous killer - with the pair now having no physical or virtual visits in three years.
Prior to the ending of the pair’s relationship, Dwyer had Ms Davidson officially listed as his "girlfriend" - and she loyally visited him in prison on a regular basis for over four years.
As a prisoner in the Midlands, Dwyer is the one who defines the relationship he has with each visitor - be it a 'partner', 'girlfriend', 'brother', 'father', 'mother' or 'friend.'
However, after the publication of our story, in which we approached Ms Davidson and asked her if she was Dwyer’s girlfriend, she never visited him again.
Sources say there were also no video calls made between the pair - and Dwyer no longer has any visitor listed as his significant other.
At the time Ms Davidson walked away from this reporter and simply said the word "no" when asked if she was in a romantic relationship with Dwyer.
Sources say Dwyer no longer has anyone listed as his girlfriend or partner on his visitor list - and the only people who now regularly visit him are his immediate family.
In the past Dwyer was in a behind-bars relationship with another woman - Russian native Victoria Andreenkova - who openly declared her love for the killer.
Andreenkova made headlines when she even proudly declared that she "did not see him as a convicted killer."
The revelation comes after Dwyer lost his appeal of his conviction for the 2012 murder of childcare worker Elaine O’Hara last week.
But sources say the arrogant killer has not given up hope of getting out - and has even told fellow lags that he intends to take his case all the way to the European courts if necessary.
"His next step is the Supreme Court, but he’s already bragging to anyone that will listen that he will get off if he takes this to Europe," a source said.
The State successfully argued in the 2015 trial that Dwyer and Ms O’Hara used the phones to text each other in the run-up to the murder.
The sicko challenged the use of such data after the EU and Irish courts ruled that the blanket retaining of such data for all phone users –including Dwyer – went against European law. But the court rejected that argument on Friday.
Mr Justice George Birmingham, Court of Appeal President, said: "In this case we are quite satisfied that the admission of the very limited call data evidence that was admitted could not conceivably be regarded as giving rise to a miscarriage of justice."
He said even if the evidence should not have been admitted at his trial, it was of little significance given the prosecution was able to establish through other evidence that the phones, which contained evidence of his plan to murder Ms O’Hara, belonged to Dwyer.
That phone data included messages from Dwyer to Ms O’Hara on several phones in which he spoke of his desire to rape and murder.
In one text, he told Elaine: "I’m a sadist. I enjoy others’ pain. You should help me inflict pain on you and help me with my fantasies."
Another text sent by Dwyer to Elaine in June 2011 read: "I want to stick my knife in flesh while aroused... blood turns me on and I’d like to stab a girl to death."
And there were dozens of sick messages. "If you ever want to die, promise me I can do it," he wrote in April 2011.
"My urge to rape, stab and kill is huge. You have to help me control or satisfy it," he told her on another occasion.
"Im having lots of thoughts about killing u", he told her in one text shortly in July 2011 – just over a year before he murdered her. He added: "I want to kill someone and also I want to hurt u as a punishment."
Dwyer fulfilled his fantasy when he lured Elaine to Shanganagh Cemetery in south Co Dublin and then brought her to Killakee Wood in the Dublin Mountains. There, he stabbed her to death before watching her die, gardai believe.
Phone evidence ultimately saw Dwyer nailed, with disturbing messages proving he was the last person to see her alive, and that he lured her into the woods of Kilakee, where he murdered her.
The at first seemingly normal Foxrock-based architect would become known as the most infamous sex killer in the country by the end of his gripping trial.
Dwyer murdered innocent Elaine for his sick sexual gratification, with the court hearing the details of his sordid past.
That included his past relationship with US woman Darci Day from Maine, who shocked the jury with her evidence at the trial.
Ms Day told how she met Dwyer on a fetish website in 2010 and how he soon told her he wanted to have sex with her and cut her throat.
Ms Day first came to garda attention when they found a document on Dwyer's hard drive entitled 'Killing Darci.'
They also discovered a photoshopped image of her with her throat cut on his drive.
