LIVE: A manhunt is underway for the person police say killed UnitedHealthcare CEO Brian Thompson.

Newly obtained video shows the moment UnitedHealthcare CEO Brian Thompson was shot at close range in Midtown Manhattan on Wednesday morning, outside a Hilton hotel.

In the chilling video obtained by FOX 5 NY and Fox News Digital, Thompson is seen walking down a New York City sidewalk when a masked man wearing a black hoodie sweatshirt and a backpack walks up behind him and raises a handgun with glove-covered hands.

At one point, the gun appears to jam, and the assailant moves toward a struggling Thompson as he attempts to shoot.
