In 2021, Nathalie Turquey, an investigating judge who had taken over the Le Grêlé case in 2014, requested the summons of 750 gendarmes who had been active in the Île-de-France region at the time of the original crime spree, in which each man was asked to submit a DNA sample. On 24 September 2021, Vérove received his summons via telephone and quickly fled his home in La Grande-Motte; his wife reported him missing on 27 September. Vérove rented an apartment in the coastal commune of Le-Grau-du-Roi, where he committed suicide by via overdosing on alcohol and barbiturates on 29 September 2021.
