An Altoona police officer was the only witness on day two of a crucial pretrial hearing. The hearing will decide what evidence can be used in the New York murder trial of Luigi Mangione. Mangione is charged with second-degree murder in the shooting death of United Healthcare CEO Brian Thompson.

His defense argues evidence from his Pennsylvania arrest was illegally obtained. The prosecution presented new body camera footage from that December day.
Bodycam Footage Reveals Arrest Details and Officer’s Doubts
Officer Joseph Detwiler testified about responding to a 911 call from an Altoona McDonald’s. A manager reported a customer who looked like the suspected New York shooter.
Detwiler said he was skeptical. He texted his lieutenant a joke about earning a hoagie for catching the suspect. The officer did not use lights or sirens en route.
Bodycam video showed Detwiler and his trainee approaching Mangione. Detwiler testified he identified Mangione “immediately” from news coverage. Mangione initially gave a false name and presented a fake New Jersey ID.
In the footage, Mangione calmly ate a hashbrown and later a steak sandwich. He told officers he was homeless. Detwiler admitted he lied, telling Mangione police were called for “lingering.”
Cross-Examination Focuses on Police Tactics and Muted Audio
Defense attorney Karen Friedman Agnifilo pressed Detwiler on his actions. She suggested he positioned himself to block an exit, which he denied.
The cross-examination highlighted moments Detwiler muted or turned off his bodycam. Friedman Agnifilo questioned if this was to discuss strategy off-record. Detwiler stated muting was routine for administrative talk.
She also made him repeat the times he was not truthful with Mangione. The defense aims to show the investigation was improperly conducted from the start.
According to the Associated Press, such suppression hearings are critical. Excluded evidence can dramatically weaken a prosecution’s case. The judge has sealed the exhibited evidence from public view to protect trial fairness.
The outcome of these hearings will directly shape the evidence presented at the Luigi Mangione trial. The defense’s motion challenges the foundation of the prosecution’s case.
