I had to do some reminder reading, but the clerk said that her companion at the store was another Indian woman that was about the same age as Sneha. If that person exists among the other victims, I would think that would be fairly easy to isolate.
I feel like her husband did a real disservice to this case by trying to whitewash her reputation. Her shopping trip footage is in this video. As some other Reddit poster says, her husband is the one who says that no one was with her after watching all the CCTV. Would he admit it if he did see someone???
