Thank you JHarlin for this photo! From what I understand from looking at Google Earth, the small airport is to the back right side and the building across from the church is a private residence, is that right? (Still hoping that the place across the street has cameras of some sort.)
Someone local mentioned before that the perp could have gone either way on 287 which would have had them pass by businesses with surveillance cameras--a gun store or a Whataburger depending on which direction they drove. (Again, hoping that there is something on their cameras!) **Unless they were on an ATV or something like that which I don't believe is the case based on LE saying in the beginning that a portion of the car was caught on footage but was too grainy to be released to the public/or decipher make or model.
