The suspected UnitedHealthcare CEO killer planned his attack well – but made crucial mistakes, experts say

Elbahrain.net But the man suspected of killing UnitedHealthcare CEO Brian Thompson on a New York City sidewalk managed to evade capture for days – puzzling even law enforcement experts.

“What surprises me is how well planned the actual attack was, and at the same time how sloppy the killer was in his movements – in his showing his face, in leaving behind items,” said Steve Moore, a retired FBI supervisory special agent.

“There’s kind of a dichotomy. It’s almost as if he read a book on how to do one of these attacks and didn’t read it carefully. He just made serious mistakes as he went along.”

The suspect’s evasion ended Monday at a McDonald’s in Pennsylvania – where police arrested Luigi Mangione in connection with the killing.

Here’s a look at what police say are the suspect’s key moves, the evidence he left behind, and what experts say about his strategy:

Detectives from the New York Police Department traveled to Georgia and reviewed surveillance footage from the Greyhound station in Atlanta – but saw no sign of the suspect, law enforcement officials told CNN. The detectives returned to New York.

Investigators are still trying to determine where the suspect boarded, said John Miller, CNN’s chief law enforcement and intelligence analyst.

He arrived early and stayed in a hostel – again, paying cash: The suspect arrived at the Port Authority bus terminal in Manhattan on November 24 – 10 days before the killing, authorities said.

It appears the suspect used cash throughout his 10 days in New York, during which he finalized plans for the killing and his escape.

He diligently wore a mask … and then lowered it: The suspect was seen on numerous public surveillance cameras with his jacket hood over his head and a mask over his face.

But a rare image of the suspect’s unmasked face was captured on surveillance video when a hostel employee flirted with him and asked him to lower his face mask, a law enforcement official told CNN.
