What we know about Luigi Mangione, suspect charged in UnitedHealthcare CEO’s killing

Luigi Mangione has been charged with murder in last week’s deadly shooting of UnitedHealthcare CEO Brian Thompson. The 26-year-old, who was identified earlier as a person of interest, was arrested on firearms and other charges in Pennsylvania on Monday after being spotted at a McDonald’s in Altoona amid a massive manhunt for the shooter.

Here’s what we know about Mangione:

Luigi Mangione wrote in notebook he considered using bomb, sources say

Two law enforcement sources told CBS News that authorities recovered a notebook from Mangione at the time of his arrest. The sources said in the notebook he wrote that he considered using a bomb but decided on a shooting because it would be more targeted and would not put innocent lives in danger.

Mangione’s fingerprints match prints found near shooting scene, police say

Fingerprints found on a water bottle and protein bar near where Thompson was killed match the fingerprints taken from Mangione when he was booked into jail in Pennsylvania, NYPD Commissioner Jessica Tisch said Wednesday.

Investigators also matched a gun that police found with Mangione in Pennsylvania to three shell casings from the shooting in New York, Tisch told reporters during a news conference with New York Mayor Eric Adams and other officials.

The fingerprint match was first reported by CNN. It’s the first publicly announced forensic evidence linking Mangione to the crime scene.

Mangione’s mother filed missing person report for him before shooting

Days before the Dec. 4 shooting, Mangione’s mother filed a missing person report for her son with the San Francisco Police Department, a person close to the investigation told CBS News.

Mangione was spotted and arrested in a McDonald’s

Mangione, who police said went to Pittsburgh and then Altoona after leaving New York, was arrested at a McDonald’s after a customer alerted an employee who called police. Officers questioned Mangione, who they described as acting suspiciously.

According to court documents, the Altoona officers found Mangione sitting at a table in the back of the McDonald’s wearing a blue medical mask and looking at a laptop with a backpack on the floor near the table. When the officers asked him to pull the mask down, they recognized him from photos released to the media.

Mangione was carrying multiple fraudulent IDs and a U.S. passport, Tisch said at a news conference. One of the IDs matched the fake New Jersey ID that the shooting suspect used to check into a Manhattan hostel before the shooting, the commissioner said.

When the Altoona officers asked Mangione for his ID at the McDonald’s, he gave them the New Jersey ID, according to an affidavit submitted with the criminal complaint. When one officer was checking the ID with dispatchers, the other asked Mangione if he had been to New York recently, and Mangione “became quiet and started to shake,” according to the affidavit.

Mangione provided his real name after he was told he would be arrested if he lied about his identity, according to the affidavit. When an officer asked Mangione why he lied about his name, he allegedly said, “I clearly shouldn’t have.”

Officers found a gun and a suppressor that were consistent with the weapon used in the shooting of Thompson, Tisch said. Police said the gun found in his backpack appeared to be a 3D-printed ghost gun, with a loaded Glock magazine with six 9 mm full metal jacket rounds and a 3D-printed silencer. Clothing and a mask consistent with those of the suspect in the case were also recovered, police said.
