Luigi Mangione's Suspected List of Plans for Days After Shooting Revealed

Marking one year since the killing of United Healthcare CEO Brian Thompson, Luigi Mangione appeared for the third day of pre-trial suppression hearings at New York State Supreme Court. Mangione, considered the main suspect in Thompsons shooting, was apprehended at a McDonalds in Altoona, Pennsylvania on December 9, 2024, after a five-day search.

The defense, led by Karen Friedman Agnifilo, is challenging the admissibility of evidence collected during Mangiones arrest. Mangione has pleaded not guilty to all state and federal charges. The items seized included a backpack containing a 3D-printed firearm, a silencer, electronic devices, and notebooks reportedly authored by Mangione.

During Thursdays session, the prosecution called Altoona officer Tyler Frye to testify. Frye was one of the two responding officers after a 911 call from McDonalds patrons who reported that a masked man inside resembled images of the UHC shooter. So far, the court has reviewed bodycam footage from officers on site and at the precinct, audio recordings of the 911 call, and photos of items recovered from Mangione.

Among the evidence is a handwritten checklist allegedly found in Mangiones backpack. In bodycam footage, a police officer at the Altoona precinct notes that the checklist indicated Mangione planned an "intel check-in" the following day, December 10, and that he had purchased USB drives and a digital camera at Best Buy on December 8. The officer also referenced a survival kit. While a photograph of the checklist was shown in court, it has not been made public.

The checklist reportedly listed December 8 with Best Buy noted beneath it, along with small sketches and items such as hot meal, water bottles, and trash bag(s). Notes for December 9 included emails, AAA batteries, and a line suggesting Archive LNM accts (LI, X), possibly referring to archiving social media accounts like LinkedIn and X.

Additional evidence included a Greyhound bus ticket dated December 4 from Philadelphia to Pittsburgh under the name Sam Dawson, a Visa gift card, and a SEPTA transit ticket for December 4, the day of Thompsons murder. Mangione had provided a fake ID under the name Mark Rosario, which had allegedly been used at a New York City hostel before the shooting.

In court, Mangione wore a grey suit with a white shirt and took detailed notes on a yellow legal pad. Newly entered bodycam footage shows him being searched at the Altoona precinct, with items found on him, including a jar of Skippy peanut butter, a Hawaiian-print wallet, and a pocketknife.

During intake, Mangione identified himself as homeless and unemployed from software company TrueCar. He provided a redacted mailing address and his mothers phone number, though he could not give her current residence, as his parents had recently moved.

Defense attorney Jacob Kaplan cross-examined Officer Frye, highlighting that Mangione had invoked his right to remain silent when asked about the backpack contents. Frye confirmed officers are trained to use deception in questioning. Another arresting officer admitted misleading Mangione about the reason for their call, claiming it was due to loitering rather than suspicion he was the UHC shooter.

Judge Gregory Carro overturned a prior ruling to seal all evidence, stating that both prosecution and defense would agree on which materials could be released to the public.
