Footage of the killing of UnitedHealthcare CEO Brian Thompson on Wednesday morning shows the gunman's silenced pistol jams in the middle of the ultimately deadly attack.
The gunman can be seen calmly walking behind Thompson, who was in New York City for the company's annual investor meeting, before shooting him in the back. As Johnson tumbles and falls to the ground, the killer struggles with the gun for a few moments before managing to shoot him again.
