Part 1/6:

Manhunt for UnitedHealthcare CEO's Killer

The investigation into the shooting death of UnitedHealthcare CEO Brian Thompson has escalated, as authorities declare it a premeditated attack. The shooting occurred outside the Hilton Hotel in Midtown Manhattan on Wednesday morning, as the busy workday began. Security footage captured the moment when the gunman targeted Thompson, who was set to speak at an investor conference at the hotel that day.

The NYPD's investigation has revealed disturbing details, including shell casings found at the scene inscribed with the words "deny," "defend," and "depose." These phrases have led law enforcement to believe that the shooting was targeted specifically at Thompson, although the motive remains unclear at this time.
