PER-BAYOUMI
Omar al-Bayoumi
Omar Albayoumi · OAB
Saudi national living in San Diego in 2000. Assisted Nawaf al-Hazmi and Khalid al-Mihdhar with housing and banking after they arrived in California. Described by the 9/11 Commission as gregarious and an unlikely clandestine operative; later FBI analytical products describe him as a paid cooptee of Saudi intelligence. Those two assessments are stored as competing evidence, not as a resolved identity.
Primary test subject of Phase 1. No criminal conviction in this corpus.
Witness statements (unmerged)
