In short:

UnitedHealthcare chief executive Brian Thompson was shot dead out the front of a hotel on Wednesday in what police are calling a "premeditated, targeted attack".

The first unmasked photographs of a person of interest in the case have been released by the New York Police Department.

Multiple US media organisations, citing unnamed investigators, say the ammunition used to shoot Mr Thompson were inscribed with the words "deny," "defend" and "depose".
