I don't understand the pin on the map thing or what, exactly, can be determined about someone's location based on cell phone pings. I always thought that cell locations were usually based on triangulation between nearest towers but, I guess, that's not correct or the only way it's done. Some places must have just one tower, right? So, when a phone shows it's connected to any tower, how is it determined where someone is/was precisely standing when the towers cover such a broad area? I've followed two cases here, both Idaho locations, where in one the phone was pinpointed exactly on the spots where bodies were buried (Vallow-Daybell case) and another where the phone was triangulated to a rather wide area (Kelsey Berreth case). I'd like to better understand this.
