‘I need to whack a CEO’: Why a backpack may resolve Luigi Mangione’s destiny
On an exclusive episode of the Daily Mail’s The Trial podcast, senior US crime correspondent Kayla Brantley dissects the high-stakes legal battle over Luigi Mangione‘s backpack and the damning evidence prosecutors say was found inside.
Mangione, 27, is accused of gunning down UnitedHealthcare CEO Brian Thompson outside a Manhattan hotel on December 4, 2024.
Following a five-day nationwide manhunt, Mangione was arrested eating breakfast at a McDonald’s in Altoona, Pennsylvania, after suspicious customers recognised him and alerted staff, who dialled 911.
Police seized a backpack from Mangione when they arrested him, and it has become the centrepiece of pre-trial hearings that began in early December.

Speaking to podcast host Caroline Cheetham, Brantley breaks down what was inside the backpack and why its exclusion could have major implications for Mangione’s upcoming state murder trial.
‘Inside the backpack was a 3D-printed gun, ammunition, a notebook, $7,000 in cash, a knife and some fake IDs,’ Brantley said.
‘What Luigi’s team is arguing is that all of that was seized and looked through without a warrant – so it should not be admissible in court.’
She explained that Mangione’s defence claims police did not seek a search warrant until seven hours after they had already searched his backpack.
‘All of that evidence will be key – you have a murder weapon, ammunition, the notebook allegedly included a manifesto,’ she said.
‘One of the quotes inside was that Luigi wanted to ‘whack a CEO’. Whack, meaning to kill or murder. That’s motive.
‘If none of that can be brought forward in the trial, the prosecution would have to go another route.’
Mangione’s defence team also argues that he was not read his Miranda rights until 20 minutes after police began questioning him.
Officers who arrested Mangione at the McDonald’s have since testified that they searched his belongings immediately to check for any weapons or explosives – standard police protocol.
However, the defence rebutted this claim, arguing that if police genuinely feared explosives, they would have evacuated the area and called a bomb disposal unit.
Brantley sympathised with the arresting officers, pointing out that emotions would have been running high as they tracked down the suspect in ‘the biggest manhunt of the year’.

‘This had been going on for five days’, she added.
‘Everyone knew at that point what had happened. If you think you’ve found the suspect, you’re going to assume they’re dangerous.
‘A gun was found there, so he was armed.’
Arguably the most damning piece of evidence inside the backpack was Mangione’s notebook, which prosecutors have described as a manifesto.
The notebook contained pages of handwritten entries railing against the health insurance industry, with one passage allegedly stating ‘these parasites simply had it coming’.
Prosecutors say the notebook also had detailed planning notes about targeting a CEO at an investor conference.
Brantley said: ‘Prosecutors described a to-do-list of tasks, such as an escape plan and how to avoid surveillance cameras.
‘These are things that the prosecution could argue represents premeditation.’
