Episode notes
Location Data Reveals Probabilistic Social Graphs
- Mike Yeagley used commercial location data to build probabilistic social graphs linking devices to Epstein's island and US addresses.
- He emphasized the data gives investigative leads but is probabilistic, not courtroom evidence.
Tracing Devices From Island To Home
- Yeagley traced devices that dwelled at the island and then appended identity by matching dwell locations like home and workplace.
- He cautioned this yields probability-based identity resolution, not definitive ownership.
Staff Devices Offer Untapped Witness Leads
- Yeagley found staff and victims on Epstein's island could be segmented by device behavioral patterns like night-shift dwelling.
- He noted these staff are key witnesses often overlooked in mainstream coverage.
