I'd bet they make an arrest of these two within a two weeks.
Yellow jacket is the witness who failed to say a word and likely knows the suspect who is wearing the blue and white knit cap. That individual needs to be taken off the streets. They couldn't ask for better pics of these two.
Yellow jacket has the deader eyes of the two. Wouldn’t be surprised to learn she has a lengthy record, assuming she’s been in this country for any length of time and assuming that she even has a fixed ID. They’re both probably flight risks.
