Customer says woman who was shot, killed inside store appeared distressed before her death

“The day that I came here, I talked to her. I said, ‘are you OK?’ And she said, yes, and I knew she wasn't OK. So she went around the corner, and she was texting, and I say, 'are you OK? She said yes and that's the last time I see her. Then I find out that she got killed,” the customer said about 25-year-old Irma Rivera-Martinez.
