I was not familiar with that case. I am, however, familiar with the Churches of Christ, having grown up in them. Church of Christ member get in petty disputes, usually over stupid little issues such as marriage, divorce, and remarriage. But when disputes arise, the typical result is a church split, not a killing.
This particular congregation is what we in the CoC call a "liberal" congregation. That means that their rules aren't as strict as the historical CoC, but they probably still seem strict to those outside the denomination. Here's what tells me they are liberal: 1) the sign says "Creekside Church, a church of christ community." A more-traditional congregation would be called "Creekside church of Christ." (Note the weird capitalization of that name.) 2) the church's website shows a pretty modern worship experience, with a "praise team" and
musical instruments. I could go on, but that's plenty to establish the case.
Now, it
is possible that this killing was the result of a very angry Church of Christ member--someone ANGRY about the musical instruments and modern worship**--who broke into the church building to vandalize or whatever, and then Missy just happened to show up at the wrong time. Then let's say Missy had a CCL, pulled her gun on him/her, the perp also had a gun and they had a little shoot-out. Far fetched? Yes. I don't think that is what happened, but time will tell.
