I followed the Murdaugh murder case a while back and that level of evidence was critical

The father killed his family and had a pretty good shot at sowing reasonable doubt until they pulled his sons phone telemetry and it showed the son unlocking his phone and checking socials at a time that conflicted with the dads story.

Phones truly are a surveillance dream. You couldn’t ask for a more invasive tracking device, and people love it. You couldn’t pry a phone away from most people these days
