According to news articles, that was Angela Williams entering the aisle in the video. Here are two examples:

About 55 seconds later, Angela Williams entered the pets aisle with two of her young children. Crawford stood totally still at the other end of the aisle with the rifle at his side, pointed at the floor.

Angela Williams, who can be seen in the Wal-Mart surveillance video from the night of the incident, entered the same aisle as Crawford (prior to police arrival) and left after she appeared to notice the rifle Crawford was holding. After police fired two shots at Crawford, she left Wal-Mart and suffered what Mark Piepmeier – the special prosecutor who presented evidence from the case to a special grand jury – called a heart attack.

FTR: I know nothing about those two sources. So, maybe you can find a source that says the woman in the video isn't the victim.
