Police were doubtful of tip that led to Luigi Mangione's arrest

December 3, 2025

Pennsylvania police officer Joseph Detwiler testified in court about responding to a tip that Luigi Mangione, the suspected shooter of UnitedHealthcare CEO Brian Thompson, was at an Altoona McDonald's. Despite initially being skeptical and joking with his supervisor about the tip's legitimacy, Detwiler discovered the man at the restaurant matched the description and was wearing a mask while eating. After requesting identification that proved fake and asking the suspect to remove his mask, Detwiler recognized him as Mangione and detained him.

Who is affected

Luigi Mangione (the defendant facing state and federal murder charges)
Brian Thompson (UnitedHealthcare CEO who was killed)
Brian Thompson's family (described as a father of two)
Officer Joseph Detwiler and his supervisor/partner (Altoona, Pennsylvania police)
The McDonald's restaurant manager who called in the tip
McDonald's customers who spotted the suspect

What action is being taken

Pretrial hearings are ongoing to determine if evidence from Mangione's arrest is admissible
Defense attorneys are calling witnesses to testify
Mangione's legal team is pressing Officer Detwiler on identification procedures
The defense is pushing to bar the federal government from seeking the death penalty

Why it matters

This case sparked an interstate manhunt and generated significant public debate about the for-profit health insurance industry in the United States. The admissibility of evidence, particularly the gun and notebook allegedly containing Mangione's motive, will be crucial in determining whether prosecutors can proceed with their case and potentially seek the death penalty.

What's next

The pretrial hearing is expected to continue for several days, with defense attorneys planning to call additional witnesses to support their motion to suppress evidence from the arrest.
