UnitedHealthcare CEO Brian Thompson​'s killer may have fled New York: Police

New York: New York police said on Friday they believe the man suspected of gunning down a top health insurance executive may have fled the city on a bus following the brazen daylight murder.

The development deepens the mystery surrounding the fresh-faced suspect, an image of whom was released by investigators Thursday and who has now been on the run for almost three days.

The masked assailant was caught on camera entering a bus station in a northern neighborhood of Manhattan in the wake of Wednesday's slaying, but he could not be identified exiting the facility on foot, a spokesman said.
