New York police have released two new photos of the suspect they say is wanted for questioning in connection with the murder of UnitedHealthcare CEO Brian Thompson, reports with the BBC.
The individual is wearing dark clothing similar to that of the attacker and does not have his face covered in the latest images.
Authorities are continuing to search for the perpetrator, using new footage, the use of facial recognition technology and a discarded phone to identify and track down the suspect.
Investigators also found that the bullets fired at the company's chief executive had words etched into them.
Investigators have announced that the words "deny", "protect" and "leave" were written on the shell casings found at the scene of the attack.
Thompson, head of the largest private insurance company in the United States, was in New York getting ready to speak at an investor conference.
