French media published a photo from the police stakeout, which shows several of the men having coffee and chatting at a Parisian café that winter, just before their arrest.
The question that remains – and which will undoubtedly be explored doing the trial – is just how the gang got wind of Kardashian’s schedule.
Court documents seen by the BBC show that both Khedache and Abbas stated that all the information they needed was posted online by Kardashian herself, whose very career was built on sharing details about her life and movements.
But how did the gang know that on the night of 2 October Kardashian would be alone in her room, without her security guard?
The documents indicate police believe Gary Madar, whose brother Michael’s firm had provided transportation and taxis to the Kardashians for years, was an accessory to the heist and that he had fed information to the gang about Kim’s whereabouts.
Mr Madar was arrested in January 2017. His lawyer Arthur Vercken vehemently pushed back against the accusations, telling the BBC that “since the start the case was built on assumptions, theses, theories – but no proof [of Madar’s involvement] was ever found”.
He added that although the Madar brothers exchanged texts about the Kardashians during Fashion Week it was just because they were “bored” and that when the heist took place Gary was asleep.
Gary’s brother, Michael, is not a defendant.
“Five men did this. You don’t think one of them was keeping an eye on who was coming and going from her hotel?” he said, suggesting that Mr Madar had only been arrested “to prove that the French justice system works”.
