I read that here as well but didn't know where that came from and Google searching wasn't much help. Turns out it was in the link of a FB live video from reporter Maria Guerrero posted here just before the sash was mentioned in a post. However, in the report, it does not specify that it was the mother OR that anything was being carried in the sash. Neighbors surveillance videos were being discussed by Guerrero just before this but it does not specify if this is what the neighbor saw himself at 7:27 or what he saw after the fact when reviewing personal surveillance footage. It also doesn't specify which street.
16:30 mark on this video:

"We spoke with one neighbor, uh one resident in this subdivision who said at 7:27, he saw who he describes as an Indian woman with like a sash around her chest walking in the street very quickly at 7:27"
(JMO) Could be a different woman entirely, could be the mother looking for her child, or could be the mother up to no good. I'd be interested to know if the sash was a baby wrap or baby sling of somesort or perhaps a piece of traditional clothing?
