Gendarme admits copy-paste error at Jubillar trial
During the tenth day of Cédric Jubillar's trial at the Tarn assizes, Major Gilles Loïs confessed a blunder in the phone data analysis of Delphine Jubillar's lover. This error undermines a key element of the prosecution regarding the night of the disappearance. Additionally, an expertise on the victim's broken glasses suggests physical violence.
The trial of Cédric Jubillar, accused of murdering his wife Delphine who disappeared in the night of December 15 to 16, 2020, in Cagnac-les-Mines, saw a major development on October 7, 2025. Major Gilles Loïs, a telephony analyst for 15 years, was recalled to the stand by President Hélène Ratinaud after the defense raised an anomaly. He admitted: 'It’s an error on my part,' explaining a hasty 'copy-paste' that included Donat-Jean Macquet's number, Delphine's lover, in the list of 551 lines active between 10 p.m. and 6 a.m. on the night of the disappearance.
Loïs, who worked on 4700 initial numbers from January 2021, narrowed the list to 216 by excluding local residents. Macquet, based in Montauban, should not have been included but appeared as Delphine's correspondent that afternoon. 'I did a copy-paste and didn’t verify,' he confessed, embarrassed. The president expressed outrage: 'How could this error happen?! No one checks your work?!' The defense, through Me Emmanuelle Franck, retorted: 'Are we supposed to take your word for it?', highlighting the inconsistency.
This blunder undermines the crucial analysis, as the defense claimed Macquet's phone had pinged near the Jubillars' home, an element allegedly missing from the file. Meanwhile, DGA expert Christophe L. analyzed Delphine's broken glasses: 'From 83 joules, we achieve a similar break to Delphine Jubillar's frame,' equivalent to an adult punch. The damage, incompatible with a fall or a six-year-old's action, suggests human force like a fist or foot. Questioned, Cédric Jubillar evaded: 'I can’t explain, they’re not my glasses.'
Witnesses, including neighbors like Guillaume T., described a possible movement of Delphine's Peugeot 207, with condensation indicating a body's presence. An engineer explained the fog as resulting from 'thermal shock' by a warm body in a cold cabin. Colleagues and relatives portrayed Delphine as dedicated and unlikely to flee, while Cédric's post-disappearance behavior raised doubts.
