Police are stressing that they have no evidence to suggest that 8-year-old Sandra Cantu was kidnapped.
As the previous post suggested while acknowledging its speculative nature, however, kidnapping is a distinct possibility. And it's certainly on the mind of many parents, even if such occurences are rare indeed. (Again, part of the point of the most recent post.)
Offically, though, Sanda is simply missing. Hence no Amber Alerts.
