Belorusov, who denies murder, had broken up with her months before and got in touch claiming he had found a new home for her and wanted to pay back money he owed her, the jury heard.
His DNA was found on a ligature tied around her neck after he was arrested in Estonia six days later and extradited back to the UK on March 20, the jury heard.
Mr Glasgow said he had accessed the internet via his phone at his alleged victim's home on March 4.
He added: " In other words, having killed her and buried her in the garden, he sent false messages from her phone to cover his trans and remained at her home address until he thought it safe to leave on the Monday morning.
"Everything he had said to her friends and the police was a lie, and he lied because he had murdered Laureline Garcia-Bertaux.
"It is the Crown's case that, no matter what may have happened during the weekend that Kirill Belorusov spent with Laureline Garcia-Bertaux (double corr), there is nothing that this defendant can say to excuse what he did to her.
