A former FBI supervisor speculated about the reason for the killing of UnitedHealthcare CEO Brian Thompson and said his itinerary could have easily been tracked.
Robert D'Amico, who now works as a security consultant, told NBC News that the attack was likely a personal vendetta against UnitedHealthcare and that "even a layman" could find out his location. "There's so much on the internet now and people put so much out there," D'Amico added.
