Cell Phone Tracking by Non-State Actors

This is interesting:

Adding credence to the theory that Brooklyn landlord Menachem Stark was kidnapped and murdered by professionals, a law enforcement source tells the Post that the NYPD found a cell phone attached to the bottom of his car, which could have been used to track his movements.

This is interesting. Presumably the criminals installed one of those "track your children" apps that transmits the phone's GPS data to some database somewhere.
