In case you were wondering--I sure was--what happened to Marisol Valles García, the 20-year-old Mexican woman/criminal-justice student who became police chief in a town because nobody else wanted the job... here's an update in the Times. Nothing too revelatory... but at least she's still alive. Though there's also a chance she hopped over the border.
Update, March 7: I just heard on the NewHour that she was fired. Turns out she did cross the border "for personal reasons." Well, it was fun while it lasted. ...I wonder how she did before the left?
