Luigi Mangione was denied bail in Pennsylvania after being charged in Brian Thompson's murder
HOLLIDAYSBURG, Pa. – Luigi Mangione, the man charged with murder in the death of UnitedHealthcare CEO Brian Thompson, broke his 24 hours of silence with an outburst as he was escorted into a Pennsylvania courthouse, where he challenged his arrest.
"It's completely out of touch, and an insult to the intelligence of the American people and its lived experience," Mangione shouted, prompting his detail of about 10 officers to hurry him inside.
Dressed in an orange jumpsuit, Mangione appeared unfazed. He was seen whispering with his attorney, Thomas Dickey, glancing at reporters and mumbling to himself at the Blair County Court hearing around 2 p.m.
Prosecutors say he had $8,000 U.S. cash; $2,000 foreign cash; masks, and a passport on him – in addition to a "ghost gun" with a silencer resembling the weapon used to kill Thompson – when he was apprehended by police in Altoona on Monday.

Dickey argued that his client had masks because "some people still have the COVID fear."
The 26-year-old was denied bail and will remain incarcerated at SCI Huntingdon until his attorney files a writ of habeas corpus, challenging whether he is being lawfully detained.
Mangione was taken into custody after he was recognized by an observant patron at an area McDonald's around 9:15 a.m. Monday. The Ivy League-educated software engineer refused to speak with investigators on Monday, and was placed in a holding cell after hours of attempted questioning.
