Investigators have not yet publicly identified the gunman who ambushed the 50-year-old insurance executive early Wednesday.

Summary

UnitedHealthcare CEO Brian Thompson was fatally shot in a targeted attack outside a New York Hilton hotel, with investigators describing the killing as meticulously planned.

The gunman fled on foot, then by rental bike, and possibly left the city via bus. Shell casings at the scene had words like “deny” and “defend” inscribed, hinting at a motive linked to Thompson’s work.

Experts suggest the shooter may have military or weapons experience but left key clues, including surveillance footage and discarded items.

Police are analyzing evidence, including DNA, to identify the suspect.
