The Bellingcat news agency has been registered in Higgins' name, and the latest "revealing" anti-Russian news is spread from this agency. However, these reports do not contain any evidence.
Pro-Kremlin disinformation attempting to discredit Bellingcat which has long been a thorn in the side of the Kremlin and recently presented proof that Alexei Navalny was poisoned by FSB agents. Alexei Navalny duped one of the FSB agents, Konstantin Kudryavtsev, into admitting his role in the poisoning and Bellingcat had already named him in its investigation as one of the FSB agents involved.
Ironically, no evidence is given to support the claims about a lack of evidence in Bellingcat’s reports. Bellingcat is an well-known independent group of researchers, investigators and citizen journalists which probes different subjects using open source and social media investigations. The team has won a lot of awards and prizes, for example, the European Press Prize for Investigation in 2019 and the London Press Club award for Digital Journalism in 2019 to name just a few.
All methodologies and sources used by Bellingcat are made public in their articles and case studies, see for example, this article about shipping of Sarin to Syria. The methodologies, resources and the way of collecting information presented in the investigation into the poisoning of Alexei Navalny have also been published as another article.
See more disinformation about the poisoning of Alexei Navalny such as the Navalny case is an outrageous fraud and an anti-Russian campaign and the West is using Navalny to access Russia's resources.
