Defense seeks to suppress evidence in UHC CEO killing

Luigi Mangione has been fighting to exclude contested evidence in the New York murder case over the killing of UnitedHealthcare’s CEO, with a multiweek evidentiary/suppression hearing that included a Dec. 2 proceeding and a Day 4 postponement after Mangione fell ill. Police reported finding bullets in his bag and prosecutors disclosed handwritten “notes to self,” and the judge — who said he hopes to finish the hearing this week — has indicated he will rule on the exclusion motion in May; no immediate ruling has been issued.
