[1] He was the son of Jean-Hugues Colonna, a former member of the National Assembly for the Socialist Party elected in the Alpes-Maritimes[2] and a recipient of the French Légion d'honneur.
[5] On 6 February 1998 at 9:05 pm, the prefect of Corsica, Claude Érignac, was assassinated as he exited a theatre onto rue Colonna-d'Ornano in Ajaccio.
However, an infrared camera set in the mountains of Corsica, near Vico as surveillance of a bergerie, a traditional Corsican shepherd stone hut, yielded evidence that Colonna was hiding there.
[7] On 20 June 2011, Colonna's conviction was upheld on appeal,[8] and he spent the remainder of his life in the Toulon-La Farlède detention centre.
[9] On 2 March 2022, Colonna was attacked in prison by Franck Elong Abé, an Islamist 36-year-old Cameroonian inmate, reportedly for "disrespecting Muhammad".
