The killer of United Health Care’s CEO Brian Thompson let down his mask while at a hostel in New York City and that’s why they have the photo above.

Here’s what was reported by CNN’s Kaitlin Collins:

Wow. Per @JohnMillerCNN, among the interviews law enforcement has been conducting, they spoke to 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 this photo released by NYPD today was taken.
