From the July 29 JTree
press release:
A ping of the male’s cell phone was recorded on July 27 at 4pm from a location inside the park.
In order for this to be an accurate statement, the NPS must have been told, at minimum, the distance and direction from which the cell signal originated. Otherwise, they would not have been able to know that Orbeso's phone was "inside the park." It could have been within the city limits.
It is a little weird that they apparently knew more about this ping two days after the disappearance than they know now, a month later.
“Somewhere within 10 miles of where that ping was is where that cell phone was,” Smith said.
Ten miles is a great distance, potentially placing the phone north of the highway!
