Mangione pleaded not guilty on Friday during his arraignment in the killing of UnitedHealthcare CEO Brian Thompson. Prosecutors have filed an intent to seek the death penalty.
The FBI and NYPD offered up to $60,000 for information leading to the arrest and conviction of the UnitedHealthcare shooting suspect. But cashing in on the reward is a complicated process.
The New York police commissioner also said investigators matched Luigi Mangione's fingerprints with those found on items near the scene where the UnitedHealthcare CEO was fatally shot last week.
Thompson, a 50-year-old father of two, spent two decades at UnitedHealth Group before his shocking death. Tributes are pouring in from coworkers and public officials in his home state of Minnesota.
