Health care executive’s killer evades police for fourth day as backpack, DNA and bullets offer clues into his identity

Four days after a health care executive was shot and killed in Manhattan, police are piecing together clues, including a backpack, photos, video, ammunition, DNA and more, to help zero in on a suspect, who they believe is no longer in the city.

As the investigation into the fatal shooting of a health care executive in Manhattan enters its fourth day, police are piecing together clues, including a backpack, photos, video, ammunition, DNA and more, to help zero in on a suspect they believe is no longer in the city. The shooting suspect, believed to have left New York City on an interstate bus, has not been identified or located following the fatal shooting of UnitedHealthcare CEO Brian Thompson police believe was “definitely planned,” NYPD officials told CNN on Friday. Investigators appear to be homing in on the possible identity of the suspect, two people briefed on the investigation said, but are still working to verify the information and are not yet certain they know his identity. New York City Police Commissioner Jessica Tisch told CNN on Friday authorities have gathered “a huge amount of evidence,” including fingerprints, DNA evidence and a “massive camera canvass” of the suspect’s movements throughout the city. At least two key pieces of evidence continued to evade investigators Saturday morning, including an electric bike the suspect rode and the gun used in the killing. However, authorities uncovered a backpack upon a second sweep of Central Park Friday evening, which awaits forensic lab testing in Queens, a law enforcement official told CNN.
