Agree, but cell towers cast a wide net. I think the recommendation is a 3mile separation from any personal in-pattern behavior.
Your follow-on point is also exactly right. This process (nowadays) would be pretty quick and produce a very small pool of likely suspects in a few minutes, given the right software. Four or five calls and a co-located number would be staring you right in the face. It really all depends on what sort of historical data LE is in possession of.
Laying this Amber data over top of the suspicious calls to Melissa’s sister (ie. same analytical process) and you have your perp.
