Shooter Who Killed UnitedHealthcare CEO Brian Thompson Remains at Large in Midtown Manhattan Attack. What Authorities Know So Far.

A man suspected of gunning down UnitedHealthcare CEO Brian Thompson outside a Midtown Manhattan hotel remains at large following the targeted and premeditated attack on Wednesday. The shooter arrived in New York City on November 24th and was captured by surveillance cameras at Port Authority Bus Terminal. Police have gathered footage of the suspect around the city, where he wore a mask and paid in cash. Authorities are investigating a possible link to anti-insurance sentiments, with writings found on shell casings at the crime scene echoing phrases from a 2010 book about insurance claims. The suspect fled the scene and has not been located.
