I doubt this. One reason being is that they wouldn’t know if a deputy was driving by on the highway when they placed the call. Deputy would be right there.I got what you were saying and I alluded to something similar. The 911 could have been the perp(s) toying with Cops. As in call and say nothing then hang up and bail as a means to taunt them. They may have known how long they’d have to get away after the hang up. We don’t know what the commotion was in there or how close it went on to the device that made the call. Did mom say help knowing 911 was dialed by someone? Did someone shoot her as the 911 was listening? Was Jayme pleading for her mom to be spared? We just don’t know.
Being a mile from town, peeps were actually lucky it took as long as it did for LE to arrive on scene.
