Question juridique clé
Whether preventive detention remained justified by a risk of flight
Solution extraite
Yes. The applicant's weak ties to Switzerland, French nationality, age, limited resources, and exposure to a very long custodial sentence made flight probable.
Motifs extraits
Flight risk is assessed on the totality of circumstances, not on offence gravity alone; here the cantonal court could infer a real and probable risk from the applicant's personal situation and the serious charge.
