I just re-watched this one because I'm familiar with the town. Two personal observations.
First, the editors were careful to show shots of only the most rundown, raggedy-*ss parts of town, except the outside of the city office building. You'd never know from watching this show that Altus isn't some godforsaken near-ghostown crossroads spot. It's a town of about 20,000 with an Air Force Base, decent motels, nice homes, a state college, and so forth. I bet the town fathers (and mothers) who saw this episode were mortified. Or indignant.
Second, Kelly mispronounced the town's name throughout. It's not "Ahl-tus," it's "Al-tus." Short "a" sound, not an "ah" sound.
About the show, it was interesting that an Altus cop would care about solving a "so cold it's frozen" case involving a woman from the wrong side of the tracks. I'm glad to see that.
It's good that Kelly and Yolanda and their team helped solve the case. The bully-boy abusive husband did it, which I think everybody suspected, but it took work and a little luck to build the case. Of course, when they finally caught him and he knew he was cornered, he changed from big bad bully who kept everybody in line by fear, to a whimpering self-justifying little rat. OK, maybe that was harsh. By which I mean, it's an insult to rats everywhere.
I hope the daughters get some counseling and have some good strong people in their lives who care for them. Because they've been dealt a bad hand in life.
