SO?
Where was he found??
Article doesn’t say.
I imagine the police followed his phone.
I saw a story years ago about a hacker named Kevin Mitnick who was arrested in 1995 who was traced by his phone using cell tower locations from across the country by some reporter and a university person so you can imagine that police have this ability.
Today shopping centers follow people by the cell phone. You are a dot until you buy something then they have your name and now you are a dot with a name who bought a shirt. That info is sold so you can be tracked by anyone.
