A private funeral was being held on Monday for murdered UnitedHealthcare CEO Brian Thompson as police detained a suspect in the case, a source familiar with the family’s plans told NBC News. The suspect was first caught on surveillance cameras in Manhattan, and had evaded a massive police search. However, Pennsylvania police said they had detained a 26-year-old who was caught with a gun similar to the one used in the shooting. Investigators believe he was in the city for 10 days before the shooting, at one point lifting his mask to speak to a hostel employee. A photo from the camera capturing that moment has been circulated worldwide.
