(CNN) Police release unmasked photo of person wanted for questioning in CEO shooting. Quoting,

Among the interviews they’ve been conducting, law enforcement interviewed a female employee at the hostel who said, at one point, she asked the then masked man to lower his mask while flirting with him — which is when the photos released by the New York Police Department today were captured, the official said.

The social nature of the suspect implies that he inevitably verbalized his discontent to others. In combination with the photo,  and the likely region of residence, this implies a clue soon to drop.
