Cops are yet to confirm a motive for the shock slaying of America’s biggest health insurance CEO in New York City – but the 𝓀𝒾𝓁𝓁er left behind a trail of overt clues.

The mystery murderer remains on the loose after gunning down UnitedHealthcare boss Brian Thompson early Wednesday morning in Midtown Manhattan.

The shooting has exposed mass discontent with the US healthcare system, while bringing UnitedHealthcare’s disturbing history of rejecting claims into the spotlight.

In February 2022, the Department of Justice moved to block UnitedHealthcare from acquiring healthcare tech company Change Healthcare Inc, saying the proposed $13 billion transaction would harm competition in commercial health insurance markets.

It comes after New York City Mayor Eric Adams implied police might have identified 𝓀𝒾𝓁𝓁er in their latest lead – but they’re not releasing his name yet.

When asked on Saturday whether investigators knew the mystery gunman‘s name, Adams said: ‘We don’t want to release that now,’ according to the New York Post.

The NYPD released new photographs of the assassin Saturday night. He has been described as white and around 6’1′ tall, but scarce other details have been given.

The attacker is believed to have used a rare World War Two era-inspired 9mm gun, which the New York Post reported was a Swiss-made Brugger & Thomet VP9.

The latest images of the 𝓀𝒾𝓁𝓁er appear to have been taken inside the taxi which picked him up on 86th Street and Columbus Avenue two minutes after he left Central Park.

He is survived by his wife Paulette ‘Pauley’ Thompson, 51, and their two children who live in the family’s $1.5 million home in Maple Grove, Minnesota.
