Manhunt underway for UnitedHealthcare CEO gunman

The search for the person who shot and killed the chief executive of a major US health insurance company has continued in New York.

Yesterday morning 50-year-old Brian Thompson was shot in the back in what police believe was a targeted attack.

Investigators have found the words ‘deny’, ‘defend’ and ‘depose’ written on the casings of the bullets used in the killing, but so far have only seen the gunman in CCTV images.
