What we know about Luigi Mangione, the suspect charged with killing insurance CEO

A five-day manhunt for the shooter who killed the top executive at the largest health-care insurance company in the United States came to an end Monday, after the suspect was spotted at a McDonald's, hundreds of kilometres from the crime scene, police said.

Local authorities arrested Luigi Mangione, 26, after a customer recognized him eating at the restaurant in Altoona, Pa., investigators announced Monday. Police said he was found carrying a gun matching the one used by the shooter who ambushed Brian Thompson, 50, outside a New York City hotel last week.

During a news conference on Wednesday, New York Police Department officials explained officers' efforts to catch Mangione, the circumstances of his capture and next steps for eventual prosecution.

Late Monday, Manhattan prosecutors filed murder and other charges against Mangione, according to an online court docket. Mangione faces several other charges in Pennsylvania, including forgery and carrying a firearm without a licence. He will eventually be extradited to New York to face charges there as well, police said.

Here's what we know so far.

Mangione was found with a ghost gun — a weapon that can be made at home, and is nearly untraceable — and a suppressor. He also had multiple pieces of fake identification similar to those believed to have been used by the killer, officials said, as well as similar clothes.

One of those fake IDs was the same New Jersey ID the gunman used to check into a New York hostel before the shooting.

Authorities also found a handwritten, three-page document that they said spoke to Mangione's "motivation and mindset." Chief of Detectives Joseph Kenny later said it was clear from the document that Mangione had "some ill will toward corporate America," but did not further describe what was written.

Mangione also had a U.S. passport, but investigators don't believe he had plans to leave the country. Kenny said he did not have a criminal record.

Police said investigators are still combing through his online accounts for evidence. Kenny said they watched thousands of hours of video and reviewed hundreds of tips over the last five days, using drones, K-9 teams, scuba divers, fly-over canvasses and door-to-door work to find the suspect.

The suspect proved difficult to identify because he was masked in surveillance footage. Police released a pair of photos from the back of a taxi on Saturday showing more of his upper face. 

Kenny said Mangione was born and raised in Maryland. He is from a prominent family in the state; one of his cousins is Nino Mangione, the Republican Maryland state legislator. 

Mangione went to high school at the all-boys Gilman School in Baltimore, where he was valedictorian in 2016. 

A statement posted to Facebook by Nino Mangione said the Mangione family was shocked by Luigi's arrest and offered prayers to the Thompson family.
