Authorities were analyzing a fingerprint on a cellphone found after the killing of UnitedHealthcare's CEO as suspect Luigi Mangione fought being sent from a Pennsylvania jail to New York to face a murder charge. The New York Police Department's top detective, Joseph Kenny, told CBS New York on Tuesday that no prints were found on bullets that killed Brian Thompson, but one fingerprint on a cellphone was recovered. He said the evidence was being processed and didn't say whether it appeared to match Mangione, the 26-year-old charged in the shooting last week in midtown Manhattan. Authorities have said that writings found in Mangione's possession hinted at a hatred of corporate greed. They’ve recovered a spiral notebook that Mangione kept, along with a three-page handwritten letter found when he was arrested, a law enforcement official said Wednesday. Police have not disclosed what was in the notebook. MORE: https://www.wthr.com/article/news/nation-world/unitedhealthcare-ceo-murder-suspect-fights-extradition/507-0a6c5b34-961f-4354-a905-e70dbab76ad7
