A man named Luigi Mangione, who is 26 years old, has been arrested for killing Brian Thompson. Brian Thompson was the leader of a big health insurance company. Luigi was caught at a McDonald's far away from New York City. He had a gun made by a 3D printer and a paper that showed why he did it. Luigi went to court in Pennsylvania and they said he could not leave jail.

Luigi now has to answer for the murder and other crimes related to guns. Brian Thompson was shot last week outside a hotel in New York City. The police think Luigi planned to kill Brian. Luigi was in court and looked calm. He had fake papers with him when the police found him. A person at McDonald's knew who he was from the news and told the police.

Luigi had a paper with him that showed he did not like big companies in America. The police found words on bullet cases at the place where Brian died. These words might mean Luigi did not like how insurance companies work. Luigi might go to New York to go to court there. His family is very sad and asks for prayers for everyone. Luigi was a very good student and worked in California. He lived in Hawaii before.
