"You can sit out there for four days, and nothing might happen," Paul Ciolino, a private investigator, told the Chicago Sun-Times. "If I have someone out there at $120 an hour for 14 hours a day and nothing happens, that gets expensive. But if the GPS says the car is going to a location every Thursday at 2, now you can go take a look."
Global positioning systems now cost less than $1,000 for the cheaper models. One big advantage in divorce cases is that someone who owns a vehicle can conceal a GPS device in the glove compartment or other hiding place legally.
Enrico Mirabelli, a divorce lawyer who began using GPS tracking less than a year ago, said that he now rarely obtains electronic toll-pass information because GPS is so much more detailed.
Last year, divorce lawyers were surveyed, and 88 percent reported using more information obtained electronically, including GPS and toll-pass data and records of computer use.
